Definition
Meaning
A thick, dark, viscous liquid produced by the destructive distillation (heating in the absence of air) of wood, especially pine wood. It is used for preserving and waterproofing.
Used figuratively or historically to reference traditional methods of waterproofing ships, ropes, or timber, often evoking pre-industrial or maritime contexts.
Linguistics
Semantic Notes
Refers specifically to tar derived from wood, as opposed to 'coal tar' or 'mineral tar'. The term is countable when referring to types or batches (e.g., 'different wood tars'), but often used uncountably for the substance.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with general 'смола' (resin) or 'дёготь' (which can be birch tar or generic tar). 'Wood tar' is specifically 'древесный дёготь' or often 'сосновый дёготь' if from pine.
Common Mistakes
- Using 'wood tar' interchangeably with 'tree sap' or 'resin' (which are naturally occurring, not distilled). Confusing it with 'asphalt' or 'bitumen' (which are mineral-based).
