Provisional rating
A provisional rating is an early estimate of strength built from only a few games, which is allowed to move quickly until enough results exist to make it reliable.
When you have played few rated games, a rating system knows little about you, so it treats your number as a rough first guess and lets it move fast. Each organization draws the line differently, and the word itself is used less than it once was.
FIDE publishes a first rating only after at least five games against rated opponents, which may be pooled from several tournaments within a span of not more than 26 months (Rating Regulations, clause 7.1.4). That initial rating is capped at 2200 (clause 8.2.3), and K stays at 40 until 30 games are completed (clause 8.3.3).
US Chess calls a rating established once it rests on more than 25 games. For a player with eight or fewer games it applies a special formula that its published method says used to be called the provisional formula, and an older US Chess FAQ shows a provisional rating as a slash and a game count, such as 1213/16.
Glicko-style systems signal the same uncertainty with an explicit rating deviation. Lichess marks a rating provisional with a question mark when its deviation is above 110.
Read a provisional number as a range, not a verdict: a rating built on six games can travel a long way once fifty more are played. For related ideas see the entries on K-factor, Glicko rating and rating floor.
Rating and title terms like "Provisional rating" matter once you know your next step, and the improvement plans by rating band set out a weekly routine for each rating range.

The K-factor is the multiplier in an Elo-style rating update that sets how many points a rating can move after a result; a larger K makes the rating react faster.
A Glicko rating is a rating that comes with an uncertainty value, the rating deviation, so that a player with few or old results can move faster than one with a long recent record.
A rating floor is a lowest value below which a rating is not allowed to fall, either as a list-wide minimum or as a personal level protected by an earlier peak.
A FIDE rating is the Elo-based number that the World Chess Federation publishes each month for players with rated games, with a published minimum of 1400, and it is the rating that FIDE titles are measured against.
A rating list is the published table of every player's current rating, refreshed at regular intervals so that tournaments and rankings can use one fixed snapshot.
