"As an example of borderline cases in lexical word classes, take the classification of words ending with -ing. Almost all of these words have a verb base, so it is easy to assume that all words ending in -ing are verbs. However, this conclusion is not correct. In fact, these words can belong to any of three different classes: verb (sometimes called the -ing participle), noun, or adjective (sometimes called participial adjective). Normally, the following tests can be applied to determine the word class:
Verbs ending in -ing can act as the main verb of a verb phrase, and may be followed by a noun or an adjective . . .: e.g. is eating lunch; becoming misty overnight.
Nouns ending in -ing can sometimes have a plural form (e.g. paintings), and can usually be a head noun after a, the, or some other determiner: e.g. [the banning of some chemicals], [her dancing].
Adjectives ending in -ing can appear before a noun, and can also occur after verbs such as be and become: e.g. the travelling public; it was (very) confusing. They are very often gradable, and can be preceded by degree adverbs such as very, so, and too: very forgiving, so interesting, too boring.
But these criteria cannot always be applied."
