droch-

1. bad
2. ill-, mal-

• In Irish, this affix acts both as an adjectival prefix (creating adjectives) and as an adjectival (modifying nouns). It lenites the word to which it attaches:

• ‎droch- + ‎duine (“person”) → ‎drochdhuine (“bad person”)
• ‎droch- + ‎focal (“word”) → ‎drochfhocal (“bad word”)

It is written without a hyphen except for words beginning with ch:

• ‎droch- + ‎croí (“heart”) → ‎droch-chroí (“weak heart; evil disposition, ill will”)
• ‎droch- + ‎cumann (“friendship, love; companionship, company”) → ‎droch-chumann (“bad companionship, evil association, illicit love”)
