well known, remarkable pertaining to being well known or famous because of some outstanding quality For another interpretation of γνωστός in ACT 4:16, see γνωστός[f] 58.55.
28.57 · Know · Able To Be Known
what can be known, what is evident, what can be clearly seen pertaining to being able to be known In a number of languages the phrase ‘can be known,’ expressing a capacity relating to a passive state, must be restructured in an active form. This may often be done by rendering ROM 1:19 as ‘because what people can know about God is clearly evident to these persons’ or ‘they can clearly comprehend what they can know about God’ or ‘because they can clearly see what people can know about God.’
34.17 · Association · Associate
friend, acquaintance pertaining to being a friend or acquaintance of someone, and thus enjoying certain privileges as a result of such a relation It is clear that in JHN 18:15 γνωστός implies much more than simply being ‘well known by.’ To have been simply well known by the High Priest could have been a source of danger for the disciple. It was the fact of a relationship of friendship which made it possible for the disciple to view the proceedings.

γνωστός. The late P Amh II. 1459 (iv/v A.D.) τὸ γνωστὸν τῆς πρὸς ἀλ[λήλο]υς συνηθείας, ‘the knowledge of our intimacy,”’ may be taken as confirming, so far as it goes, the ordinary LXX and NT usage of yv.—‘“‘ known”’ rather than ὁ“ knowable ”—in Rom 113. For the rare use of the word as applied to persons (Lk 244, 2349, Jn 1815) Abbott (FowrJold Gospel,
