Из википедии: "Americans tend to write Mr., Mrs., St., Dr., while British will most often write Mr, Mrs, St, Dr, following the rule that a full stop is used only when the last letter of the abbreviation is not the last letter of the complete word; this kind of abbreviation is known as a contraction in the UK"Maксим К. писал(а):Помогите определить это British English or American English
