IPA: /ˈoʊvərstrʌŋ/
KK: /ˈoʊvərstrʌŋ/
Feeling very nervous, sensitive, or tense; also refers to something that is too tightly strung, like a bow.
After the stressful week, she felt overstrung and needed a break.
Overstrung → It is formed from "over-" (meaning excessively) and "strung" (the past participle of "string", which comes from Old English "streng", meaning to stretch or tighten). The word "overstrung" means excessively tense or tightly stretched, often referring to a state of emotional or physical strain.
Think of being 'excessively' ('over-') 'stretched' or 'tightened' ('strung') — that's why overstrung means being in a state of excessive tension.
