I just can't make myself say 'burgled' instead of 'burglarized'.. it just cracks me up, no idea why.
This group of words is a bit strange --
(noun) BURGLAR
(noun) BURGLARY
(verb) BURGLE
(verb) BURGLARIZE
According to the Oxford English Dictionary, the two nouns, burglar and burglary, go back to medieval times and are described as "anglo-latin" words; that is, technical legal terms. Oddly, though, there doesn't seem to be a verb to go with them... so in recent times, verbs were created by "back-formation" from the noun burglar. In the UK, "to burgle" and in the USA "to burglarize."
Oddly, they seem to have appeared around the same time. In the OED, the first instance quoted of "burglarize" dates from 1871, and of "burgle" in 1872.
1871 Southern Mag. Apr. (Schele de Vere), The Yankeeisms donated, collided, and burglarized, have been badly used up by an English magazine-writer.
1872 M. COLLINS Pr. Clarice I. iv. 63 The burglar who attempted to enter that room would never burgle again.
