Although, historically, definition 2 was the original (derived from the French below) usage; meaning gradually changed to definition 1. More recently general usage has come to, once again, incorporate definition 2. As many older speakers will consider definition 2 incorrect, avoiding the word altogether may be advisable. The construction "not pertinent" is one possible alternative.
