'That's how it is / just so' — a compact affirmation that something is exactly as described or as it always goes. Built from 'a' (it is) and 'so' (thus), it stands alone as agreement ('a so!') or heads a statement, as in 'a so it go' (that's just how it goes). A workhorse of everyday agreement and resignation.
