Excessive indulgence in physical pleasures, especially alcohol, leading to the wasting of one's health, money, or moral character.
Linguistics
Semantic Notes
Primarily a noun. The two main meanings (waste/scattering and decadent lifestyle) are closely linked metaphorically: both involve a loss or dispersal of something valuable (energy, resources, vitality, moral fibre).
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. Both varieties use it in scientific and moral contexts.
Connotations
Equally formal and somewhat old-fashioned in the 'debauchery' sense in both regions.
Frequency
Slightly higher frequency in UK English due to more common use in 19th-century literature and its continued use in thermodynamic contexts in academia.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'расслабление' (relaxation). 'Dissipation' implies harmful excess and waste, not harmless rest. Closer to 'распутство' (debauchery) or 'рассеивание' (scattering).
Common Mistakes
- Using it as a verb (the verb is 'dissipate').
- Confusing it with 'dissolution' (which implies breaking down into parts, not necessarily wasting).
- Using it in overly informal contexts.
