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.

admonish (v.)youdaoicibaDictYouDict
mid-14c., amonesten "remind, urge, exhort, warn, give warning," from Old French amonester (12c.) "urge, encourage, warn," from Vulgar Latin *admonestare, from Latin admonere "bring to mind, remind, suggest;" also "warn, advise, urge," from ad- "to" (see ad-) + monere "advise, warn" (see monitor (n.)).

The -d- was restored on Latin model. The ending was influenced by words in -ish (such as astonish, abolish). Related: Admonished; admonishing.
