Ask (/æsk/) is an English verb meaning "to pose questions" - so it's a language-related verb.

Ask is a regular verb - it has the third person form "asks" /æsks/, the -ing form "asking", and a regular preterite and past participle "asked" /æskt/.

Ask is a catenative verb that takes a to-infinitive, e.g. "I asked to go to the bathroom". This is common in reported speech. We can in theory, say e.g. "I ask to go to the bathroom", but are fare more likely to actually ask e.g. "can I go to the bathroom?"

In accents that have the bath-trap split, this may be pronounced /ɑ:sk/
