Cognate: 4908 synetós (an adjective, derived from 4920 /syníēmi, "to understand by synthesizing") – properly, "personal" understanding that results from correlating facts (concepts), i.e. as understanding works in keeping with one's own perspective.

"Personal comprehension" (4908 /synetós) however is only sound when it follows God's word. 4908 /synetós ("understanding") apart from faith ("God's inbirthed persuasions") simply expresses the limitations (biases) of the thinker – which is the usual (negative) connotation of this term in the NT. See: Mt 11:25; Lk 10:21; 1 Cor 1:19. See 4920 (syníēmi).

[The other occasion of 4908 (synetós) in the NT, Ac 13:7, is more neutral. But even here it doesn't reflect the prudence (intelligence) that comes directly from the Holy Spirit.]

prudent.

From suniemi; mentally put (or putting) together, i.e. Sagacious -- prudent. Compare phronimos.
