Old Irish

Etymology

From Proto-Celtic *ad-, from Proto-Indo-European *h₂éd (“near, at”). Cognates include Latin ad and English at.

Prefix

ad-

1. to, towards
2. in many compounds, it has a purely intensive sense
3. augment infix used instead of ro- on verbs whose first prefix is com- and the stressed syllable starts with a consonant

   ‎con·birt (“you conceived”) + ‎ad- → ‎con·abairt (“you have conceived”) (forms of con·beir)

   ‎con·melt (“(s)he rubbed”) + ‎ad- → ‎con·amailt (“(s)he had rubbed”) (forms of con·meil)

   ‎·coscrad (“not destroyed”) + ‎ad- → ‎·comscarad (“had not destroyed”) (past subjunctive prototonic forms of con·scara)

   ‎*·cotla + ‎ad- → ‎·comthala (subjunctive forms of con·tuili (“to sleep”))

Usage notes

• ad-, when used as an augment affix, vanishes in prototonic forms due to syncope. However, its presence may be detected via the different syncope patterns between forms augmented with ad- and those that were not.
• In deuterotonic verbs where ad- is the first prefix and the next sound is /t/, the d in the prefix may be dropped in its spelling.
