The sociolinguistic context is necessary for the understanding of humour, but it is not always valid for all humorous expressions. When the sense of humour resides in a play on words, it is necessary to appeal to a linguistic intelligence to understand the humour. Besides, the translators of humorous films encounter a lot of problem in the translation or the subtitling of puns because the literal translation will not have a humorous effect among foreign spectators, and the translation of the meaning requires a lot of space and time on the screen in which humour loses its effect.
