the.com/entrant

means A person newly entering a competition, profession, or organization — someone officially on the list as having come in.

from From Latin intrare, 'to go into,' by way of French entrer. The -ant ending (from French présent participle) turns the verb into 'one who is doing the entering' — the same ending that gives English words like 'occupant' and 'applicant' their 'person who does X' meaning.
