The phrasal verb "thinned out" consists of two words:
1. Thinned: The word "thinned" is the past participle form of the verb "thin". It derives from the Old English word "thynnian", meaning "to make thin or slender". This can be traced back to the Proto-Germanic word "thunnuz" and ultimately to the Proto-Indo-European root "*ténh₂us". Over time, "thinned" came into use to describe the process of reducing the density or thickness of something.
2. Out: The word "out" in this context is an adverbial particle often used in phrasal verbs to indicate the completion or intensification of an action. Its use in "thinned out" indicates the process of thinning becoming more pronounced, extensive, or widespread.
