Jimc, who restated in improved form what I said, makes a similar
point. However, asking "Is this a taxi/taksi" is no different from
asking "Are you a baby?", "Are you a university student?". Do
answer that, you have to add tense, yielding, say: "Is this a
taxi now?", "Are you a baby now?" Clearly you aren't a baby now;
you're an ex-baby. But is a taxicab sans passenger a taksi now, or
only an ex-taxi? So really I think my original point stands.
