Verb objects (and transitive/intransitive) are another difference between the dialects. In AmE you can say “I wrote Grandma yesterday”; in BrE that would be “I wrote to Grandma yesterday”.
A lot of AmE usage is becoming commonplace in Britain thanks to the Internet, though. You’ll now see commercials in Britain that implore you to “Search ‘Fred Insurance’ for full details”. Five years ago that would have been “Search _for_ ‘Fred Insurance’”.
