What is this English word in Irish?

Like what Insect overlord said originally, because it's a username I'd go "Ciallmhar", It has the right amount of pretentiousness but yet people will understand the meaning or atleast recognise it as an Irish word

Why not go for "Saoi gan locht"?

There are a number of words that can mean wisdom, but both Foclóir Uí Dhónaill (electronic version) and focal.ie give 'críonnacht' as the primary term.

Foclóir Uí Dhónaill gives 'críonnacht' as meaning 'wisdom, prudence, shrewdness, sagacity, thriftiness, maturity, old age'.

The meaning given for 'saíocht' is a bit different: 'learning, erudition, mastery, accomplishment'.

It should be noted that one can be wise without being learned, as wisdom is really about life experience and not necessarily education, in my view.

Personally, I see 'sensible' when I read 'ciallmhar', and I mean that in the boring, predictable and uninteresting sense. But that is just my subjective view of it.
