Etymology

infrequent = in<not> + frequent<regular>

  • in: A prefix of Latin origin meaning "not" or "without."
  • frequent: From Latin frequens ("crowded, repeated, regular"), derived from frequere ("to fill, crowd").

Etymology Origin:
The word "infrequent" combines the negative prefix in- with frequent, originally describing something "not crowded" or "not repeated often." Over time, it evolved to mean "rare" or "occurring seldom," reflecting the logical opposition to regularity.
