词根:-her-, -hes-

【词根含义】:粘着,粘附

【词根来源】:-her-和-hes-来源于拉丁语动词haereo, haerere, haesi, haesus(粘着,粘附); haerere(粘着,粘附)的潜在意义还有两方面,一为“阻止”或“口吃”而造成说话做事不敏捷、不果断,此意义下的派生词haesitare(粘附,犹豫)产生的英语词根为-hesit-(犹豫);一为“粘附于上”→“继承,遗传”, 此意义下的派生词hereditare (继承,遗传)产生的英语词根有-heredit-和-herit-。

词根词缀:ad-

【来源及含义】Latin: prefix; to, toward, a direction toward, addition to, near, at; and changes to: ac-, af-, ag-, al-, an-, ap-, aq-, ar-, as-, at- when ad- is combined with certain words that begin with the letters c, f, g, l, n, p, q, r, s, and t

【相关描述】The form ad- appears in this form before a vowel and before the consonants d, h, j, m, and v. It is simplified to a- before sc, sp and st.

Before c, f, g, l, n, p, q, r, s, and t; ad- is changed to ac-, af-, ag-, al-, an-, ap-, aq-, ar-, as-, and at-.

In other words, the d of ad usually changes into the same letter as the first letter of the following root or word when it is a consonant: ad-fix becomes affix, and ad-sign becomes assign; therefore, making a double consonant.

Another example includes: attract as with ad-tract (drawn towards); so it has a double t. On the other hand when ad- precedes a vowel, as with adapt, it is simply ad-apt, with one d. For the same reason, there is only one d in adore and adumbrate, because ad- has combined with orare and umbra each of which starts with a vowel.

So, remember: since these Latin words begin with vowels and not consonants, the d of ad does not double as shown in the previous examples.
