In linguistics, periphrasis is a device by which a grammatical concept is expressed by more than one word (typically one or more function words modifying a content word), instead of being shown by inflection or derivation. For example, the English future tense is periphrastic: it is formed with an auxiliary verb (shall or will) followed by the base form of the main verb. Another example is the comparative and superlative forms of adjectives, when they are formed with the words more and most rather than with the suffixes -er and -est: the forms more beautiful and most beautiful are periphrastic, while lovelier and loveliest are not.
A comparison of some Latin forms with their English translations shows that English uses periphrasis in many instances where Latin uses inflection:
