What are some standard abbreviations?

According to the Oxford English Dictionary, some standard abbreviations include adj. for adjective, addr. for address, knowl. for knowledge, l. for line, lab. for laboratory, lang. for language, lit. for literal(ly), m. or masc. for masculine, and f. or fem. for feminine.

The list provided by the Oxford English Dictionary is of the most common abbreviations in the English language and are only used in work titles or subjects labels, rather than in speaking English or in essays, books, or letters. Specific disciplines, such as medicine or chemistry, have their own glossaries of accepted or standardized abbreviations that would be used within their respective contexts (i.e. aa for amino acids, or AA for Alcoholics Anonymous).
