regimen

REJ-uh-mun /ˈredʒ.ə.mən/
nounC1GRESATTOEFL
formalmedical

A systematic plan or regulated course of diet, exercise, or medical treatment intended to improve or preserve health.

Implies a disciplined, structured, and long-term prescribed plan rather than a casual daily habit.

The story behind the word. Directly from Latin 'regimen', meaning 'rule, guidance, or direction' (from 'regere', 'to guide or rule'). In Late Middle English, medical practitioners adopted the term to describe a systematically governed ruleset for diet and bodily hygiene.

Word relationships

  • routine: 'Routine' implies repetitive habit without the formal health or therapeutic discipline implied by 'regimen'.
  • program: 'Program' is broader and can refer to software, schedules, or events, whereas 'regimen' is specifically health/medical.
  • disorganization: Lack of order or structure.

Commonly confused with

  • regime: 'Regime' refers to an authoritarian government or ruling system, whereas 'regimen' refers to a structured health/dietary plan.
  • regiment: A 'regiment' is a military operational unit, not a health program.

Word family

  • regimental (adjective): Relating to systematic control or military units.

Collocations

  • strict regimen
  • dietary regimen

Memory hook

A REGIMEN RULES (regere) your routine so you stay disciplined. Regimen = Structured health rule

When not to use

Do not confuse with 'regime' (a government or political system) or 'regiment' (a military unit).

Fun facts

  • Although 'regime' is often mistakenly used for 'regimen' in casual speech, medical journals strictly enforce 'regimen' for health protocols.
