The name is composed of the Old Slavonic elements, stracho (fear) and mir (peace). Strachomir is the Polish form, it is first recorded in Poland in 1386 but has since fallen out of use.
It spun off the Medieval Czech and Polish male name, Strachota, which was used as a vernacular form of the Greek name, Methodius which also means “fear.” A hypothetical female form would be Strachomira.
Hypothetical Polish diminutive forms would be, Stracha, Strachot, Strasz, Straszech, Straszek, and Straszko.
The South Slavic forms are Strahimir Страхомир, Strahomir Страхимир, and Strashimir Страшимир.
