Here are some more examples of literary colloquial words. Pal and chum are colloquial equivalents of friend; girl, when used colloquially, denotes a woman of any age; bite and snack stand for meal; hi, hello are informal greetings, and so long a form of parting; start, go on, finish and be through are also literary colloquialisms; to have a crush on somebody is a colloquial equivalent of to be in love. A bit (of) and a lot (of) also belong to this group.
A considerable number of shortenings are found among words of this type. E. g. pram, exam, fridge, flu, prop, zip, movie.
Verbs with post-positional adverbs are also numerous among colloquialisms: put up, put over, make up, make out, do away, turn up, turn in, etc.
Literary colloquial words are to be distinguished from familiar colloquial and low colloquial.
The borderline between the literary and familiar colloquial is not always clearly marked. Yet the circle of speakers using familiar colloquial is more limited: these words are used mostly by the young and the semi-educated. This vocabulary group closely verges on slang and has something of its coarse flavour.
E. g. doc (for doctor), hi (for how do you do), ta-ta (for good-bye), goings-on (for behaviour, usually with a negative connotation), to kid smb. (for tease, banter), to pick up smb. (for make a quick and easy acquaintance), go on with you (for let me alone), shut up (for keep silent), beat it (for go away).
Low colloquial is defined by G. P. Krapp as uses "characteristic of the speech of persons who may be broadly described as uncultivated".  This group is stocked with words of illiterate English which do not present much interest for our purposes.
The problem of functional styles is not one of purely theoretical interest, but represents a particularly important aspect of the language-learning process. Stu-
