[adequate etymology, adequate origin, 英语词源]
adhere: [16] Adhere was borrowed, either directly or via French adhérer, from Latin adhaerēre. This in turn was formed from the prefix ad- ‘to’ and the verb haerēre ‘stick’. The past participial stem of haerēre was haes- (the ultimate source of English hesitate), and from adhaes- were formed the Latin originals of adhesion and adhesive.
=> hesitate
adjacent: [15] Adjacent and adjective come from the same source, the Latin verb jacere ‘throw’. The intransitive form of this, jacēre, literally ‘be thrown down’, was used for ‘lie’. With the addition of the prefix ad-, here in the sense ‘near to’, was created adjacēre, ‘lie near’. Its present participial stem, adjacent-, passed, perhaps via French, into English.

The ordinary Latin transitive verb jacere, meanwhile, was transformed into adjicere by the addition of the prefix ad-; it meant literally ‘throw to’, and hence ‘add’ or ‘attribute’, and from its past participial stem, adject-, was formed the adjective adjectīvus. This was used in the phrase nomen adjectīvus ‘attributive noun’, which was a direct translation of Greek ónoma épithetos.

And when it first appeared in English (in the 14th century, via Old French adjectif) it was in noun adjective, which remained the technical term for ‘adjective’ into the 19th century. Adjective was not used as a noun in its own right until the early 16th century.

=> adjective, easy, reject
adjourn: [14] Adjourn originally meant ‘appoint a day for’, but over the centuries, such is human nature, it has come to be used for postponing, deferring, or suspending. It originated in the Old French phrase à jour nomé ‘to an appointed day’, from which the Old French verb ajourner derived. Jour ‘day’ came from late Latin diurnum, a noun formed from the adjective diurnus ‘daily’, which in turn was based on the noun diēs ‘day’.
=> diary, journal

adjutant: [17] An adjutant was formerly simply an ‘assistant’, but the more specific military sense of an officer who acts as an aide to a more senior officer has now virtually ousted this original meaning. The word comes from a Latin verb for ‘help’, and is in fact related to English aid. Latin adjuvāre ‘help’ developed a new form, adjūtāre, denoting repeated action, and the present participial stem of this, adjutant- ‘helping’, was borrowed into English.
=> aid, coadjutor
admiral: [13] Admirals originally had nothing specifically to do with the sea. The word comes ultimately from Arabic ’amīr ‘commander’ (from which English later also acquired emir [17]). This entered into various titles followed by the particle -al- ‘of’ (’amīr-al-bahr ‘commander of the sea’, ’amīr-al-mūminīn ‘commander of the faithful’), and when it was borrowed into European languages, ’amīr-al- became misconstrued as an independent, free-standing word.

Moreover, the Romans, when they adopted it, smuggled in their own Latin prefix ad-, producing admiral. When this reached English (via Old French) it still meant simply ‘commander’, and it was not until the time of Edward III that a strong naval link began to emerge. The Arabic title ’amīr-al-bahr had had considerable linguistic influence in the wake of Arabic conquests around the Mediterranean seaboard (Spanish almirante de la mar, for instance), and specific application of the term to a naval commander spread via Spain, Italy, and France to England.

Thus in the 15th century England had its Admiral of the Sea or Admiral of the Navy, who was in charge of the national fleet. By 1500 the maritime connection was firmly established, and admiral came to be used on its own for ‘supreme naval commander’.

=> emir
admire: [16] Admire has rather run out of steam since it first entered the language. It comes originally from the same Latin source as marvel and miracle, and from the 16th to the 18th centuries it meant ‘marvel at’ or ‘be astonished’. Its weaker modern connotations of ‘esteem’ or ‘approval’, however, have been present since the beginning, and have gradually ousted the more exuberant expressions of wonderment. It is not clear whether English borrowed the word from French admirer or directly from its source, Latin admīrārī, literally ‘wonder at’, a compound verb formed from ad- and mīrārī ‘wonder’.
=> marvel, miracle
admit: [15] This is one of a host of words, from mission to transmit, to come down to English from Latin mittere ‘send’. Its source, admittere, meant literally ‘send to’, hence ‘allow to enter’. In the 15th and 16th centuries the form amit was quite common, borrowed from French amettre, but learned influence saw to it that the more ‘correct’ Latin form prevailed.
=> commit, mission, transmit
admonish: [14] In Middle English times this verb was amoneste. It came, via Old French amonester, from an assumed Vulgar Latin verb *admonestāre, an alteration of Latin admonēre (monēre meant ‘warn’, and came from the same source as English mind). The prefix ad- was reintroduced from Latin in the 15th century, while the -ish ending arose from a mistaken analysis of -este as some sort of past tense inflection; the t was removed when producing infinitive or present tense forms, giving spellings such as amonace and admonyss, and by the 16th century this final -is had become identified with and transformed into the more common -ish ending.
=> mind
ado: [14] In origin, ado (like affair) means literally ‘to do’. This use of the preposition at (ado = at do) is a direct borrowing from Old Norse, where it was used before the infinitive of verbs, where English would use to. Ado persisted in this literal sense in northern English dialects, where Old Norse influence was strong, well into the 19th century, but by the late 16th century it was already a noun with the connotations of ‘activity’ or ‘fuss’ which have preserved it (alongside the indigenous to-do) in modern English.
=> do
adobe: [18] Adobe is of Egyptian origin, from the time of the pharaohs. It comes from Coptic tōbe ‘brick’ (the form t.b appears in hieroglyphs). This was borrowed into Arabic, where the addition of the definite article al produced attob ‘the brick’. From Arabic it passed into Spanish (the corridor through which so many Arabic words reached other European languages), and its use by the Spanish-speaking population of North America (for a sun-dried brick) led to its adoption into English in the mid 18th century.
adolescent: [15] The original notion lying behind both adolescent and adult is of ‘nourishment’. The Latin verb alere meant ‘nourish’ (alimentary and alimony come from it, and it is related to old). A derivative of this, denoting the beginning of an action, was alēscere ‘be nourished’, hence ‘grow’. The addition of the prefix ad- produced adolēscere.

Its present participial stem, adolēscent- ‘growing’, passed into English as the noun adolescent ‘a youth’ (the adjective appears not to have occurred before the end of the 18th century). Its past participle, adultus ‘grown’, was adopted into English as adult in the 16th century.

=> adult, alimentary, alimony, coalesce, coalition, proletarian, prolific

adrenaline: [20] The hormone adrenaline is secreted by glands just above the kidneys. From their position these are called the ‘adrenal glands’ [19], a term based on Latin rēnes ‘kidney’, which has also given English renal [17] and (via Old French) the now obsolete reins ‘kidneys’ [14]. The discovery of adrenaline and the coining of its name are both disputed: they may have been the work of Dr Jokichi Takamine or of Dr Norton L. Wilson.
adultery: [14] Neither adultery nor the related adulterate have any connection with adult. Both come ultimately from the Latin verb adulterāre ‘debauch, corrupt’ (which may have been based on Latin alter ‘other’, with the notion of pollution from some extraneous source). By the regular processes of phonetic change, adulterāre passed into Old French as avoutrer, and this was the form which first reached English, as avouter (used both verbally, ‘commit adultery’, and nominally, ‘adulterer’) and as the nouns avoutery ‘adultery’ and avouterer ‘adulterer’.

Almost from the first they coexisted in English beside adult- forms, deriving either from Law French or directly from Latin, and during the 15th to 17th centuries these gradually ousted the avout- forms. Adulter, the equivalent of avouter, clung on until the end of the 18th century, but the noun was superseded in the end by adulterer and the verb by a new form, adulterate, directly based on the past participle of Latin adulterāre, which continued to mean ‘commit adultery’ until the mid 19th century.

adumbrate: see umbrage
advance: [13] Advance originated in the Latin adverb abante ‘before’ (source of, among others, French avant and Italian avanti), which in turn was based on ab ‘from’ and ante ‘before’. In post-classical times a verb, *abantiāre, seems to have been formed from the adverb. It developed into Old French avancer, and passed into English as avaunce, initially with the meaning ‘promote’.

A new form, advancer, started life in Old French, on the mistaken association of avancer with other av- words, such as aventure, which really did derive from Latin words with the ad- prefix; over the 15th and 16th centuries this gradually established itself in English. The noun advance did not appear until the 17th century.
