Words related to larceny

-y (3)
suffix in pet proper names (such as Johnny, Kitty), first recorded in Scottish c. 1400; according to OED it became frequent in English 15c.-16c. Extension to surnames seems to date from c. 1940. Use with common nouns seems to have begun in Scottish with laddie (1546) and become popular in English due to Burns' poems, but the same formation appears to be represented much earlier in baby and puppy.
burglar (n.)
"one who commits robbery by breaking into a house," 1540s, shortened from Anglo-Latin burglator (late 13c.), earlier burgator, from Medieval Latin burgator "burglar," from burgare "to break open, commit burglary," from Latin burgus "fortress, castle," a Germanic loan-word akin to borough.

The unetymological -l- is perhaps from influence of Latin latro "thief" (see larceny). Middle English had burgur (c. 1200), from Old French burgeor, burgur, also housbreker (c. 1400). Burglar-alarm is by 1840.
