For ESL learners
"roachless" is informal English meaning without a roach . It is used widely across English varieties. A more formal or neutral equivalent would be something like "without a roach " expressed in standard vocabulary. A common mistake is to assume "roachless" can replace its standard equivalent in every register; keep it for spoken or casual situations and use the formal form in writing. If you are a B2 or C1 learner, it is useful to recognise this word when you hear or read it, but think carefully about whether the situation really calls for it before using it yourself.
