What is the plural form of taxi (a taxicab)?
For example: Usually there are several taxis (vehicles) at our station. Is it correct?
Not to be confused with the differently-pronounced biological word 'taxis' /tæksɪs/ meaning the way cells respond to the environment.
Or heliotaxis, which is how a flower turns to face the sun; not a helicopter taxi.
Dictionaries give plural forms. There should be no need to ask a question here on something like that.
If the god who drove the chariot pulling the sun opened a sideline of chariots for hire, would it be heliostaxis?
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
I never hear the word taxicab used nowadays.
I agree, it's not in general use. But there was an HBO show recently called "Taxicab Confessions," which featured the drama of taxi patrons as captured on a secret camera.
