全ぜん然ぜんN5sense 1
全然 is the everyday word for 'not at all' usable in any register, while てんで is a stronger, more colloquial intensifier with the same negative meaning.
とてもN4sense 2
とても is the standard modern word for 'very', which is the meaning てんで carries only in its rare, dialectal affirmative use.
全まったくN3sense 1
まったく is a neutral, widely used way to say 'completely (not)', whereas てんで sounds more blunt and casual.
さっぱりN3sense 1
さっぱり with a negative also means 'not at all', but it leans toward describing a lack of feeling or result, while てんで is a general emphatic negator.

The origin is uncertain. It may be a sound-symbolic (mimetic) formation, but no clear derivation is known.
