happening regularly over time
Happening again and again with a regular time gap in between.
Модель уживання:
periodic [check/review/payment/event]
Поширена помилка:
Learners sometimes confuse "periodic" with "regular" meaning "ordinary" or "normal" (e.g. *a periodic customer*). "Periodic" should describe things that happen again and again over time, such as checks, payments, or meetings. Learners also mix up "periodic" (adjective) with "periodical" (noun) for magazines or journals.
Синоніми
regular (Very common word; can also mean 'normal' or 'usual', not only 'at set intervals'.)
|
recurring (Focuses on something happening again; does not always suggest a strict schedule.)
Антоніми
continuous (Describes something that does not stop or break, instead of happening with gaps in between.)

Модель уживання:

Синоніми
cyclic (Technical; emphasizes movement or change in cycles, often used in physics and engineering.)
|
regularly repeating (More descriptive phrase, less technical; stresses the exact repetition.)
Антоніми
