Pro Tip
Avoid overusing 'prolong'
In everyday speech, prefer 'extend' or 'make longer' unless writing formally. 'Prolong' sounds more technical or literary.
Gold Rule
Time-focused meaning
'Prolong' always implies extending time or duration, not physical length or size.
Formal tone
Use 'prolong' in formal writing (e.g., academic, legal, medical). For casual speech, choose simpler words like 'drag out'.
Word Origin
From Latin *prolongare* (to extend), combining *pro-* (forward) and *longus* (long). Entered English in the 15th century via Old French *prolonger*.
Usage Notes
Avoid using 'prolong' for physical extension (e.g., 'prolong a rope'). It is primarily used for time-related contexts.
