History and Etymology for verklempt
borrowed from Yiddish farklemt "depressed, grieving," past participle of farklemen "to grip, press," going back to Middle High German verklemmen, from ver-, vir-, vor-, verb prefix, here with intensive force (going back to Old High German fir-, far- FOR-) + klemmen "to press, squeeze," going back to Old High German -klemmen (in biklemmen "to block, oppress"), going back to Germanic *klammjan-, derivative from a base *klamm-, whence Old English clam, clom "bond, fetter" more at CLAM entry 1
NOTE: The spelling verklempt shows accommodation to standard German orthography.
