gnostos, gnorimos describes something made known or evident, and people recognized as acquaintances.

The dominant use marks information, events, or realities as known, made known, or evident to a stated group; a smaller cluster identifies persons as acquaintances or as known to someone. The neuter forms occur with matters announced, recognized, or clear, while masculine forms identify people in personal connection.

1. Known or made evident to others · dominant

   The neuter form is used of matters becoming publicly known or being communicated: in Acts 1:19 the event becomes known to Jerusalem's residents, and in Acts 19:17 it becomes known to Jews and Greeks in Ephesus. In Acts 2:14 and Acts 4:10, the clause calls for a declaration to be known to its hearers; in Acts 4:16 the APB renders the sign as "manifest to all who dwell in Jerusalem." Romans 1:19 places the known matter concerning God among those addressed.

2. A person known in personal connection · common

   The masculine forms designate people in relation to others. In John 18:15 and John 18:16, the same disciple is described in connection with the high priest and is able to speak to the gatekeeper; in Luke 23:49 the plural identifies those standing at a distance, and Luke 2:44 places them alongside relatives in the search.

In the Anselm Project Bible: The APB variously presents the neuter uses with "known," "let it be known," "manifest," and "clear," while personal contexts use "acquainted" and "acquaintances." These are renderings of whole clauses to the lemma.
