Expert writing Tips

Best practice

Use "several decades" to refer to a period of time longer than two decades but not so long that it would be considered "many decades" or a "century". It implies a notable but finite duration.

Common error

Avoid using "several decades" when you have specific data about the number of decades involved. If it's exactly two, say "two decades". "Several" implies an inexact quantity greater than two.

Linguistic Context

The phrase "several decades" functions as an adjectival phrase modifying a noun (e.g., "several decades of research"). It indicates a duration of time, specifying an approximate period consisting of multiple decades.
