An affix grammar is a two-level grammar formalism used to describe the syntax of languages, mainly computer languages, using an approach based on how natural language is typically described. [ 1 ] The formalism was invented in 1962 by Lambert Meertens while developing a grammar for generating English sentences. [ 2 ]
Inflectional affixes introduce a syntactic change, such as singular into plural (e.g. -(e)s), or present simple tense into present continuous or past tense by adding -ing, -ed to an English word. All of them are bound morphemes by definition; prefixes and suffixes may be separable affixes .
The first of these sentences is a basic zero conditional with both clauses in the present tense. The fourth is an example of the use of will in a condition clause [4] (for more such cases, see below). The use of verb tenses, moods and aspects in the parts of such sentences follows general principles, as described in Uses of English verb forms.

Derivational morphology often involves the addition of a derivational suffix or other affix. Such an affix usually applies to words of one lexical category (part of speech) and changes them into words of another such category. For example, one effect of the English derivational suffix -ly is to change an adjective into an adverb (slow → slowly).
Unlike derivational suffixes, English derivational prefixes typically do not change the lexical category of the base (and are so called class-maintaining prefixes). Thus, the word do, consisting of a single morpheme, is a verb, as is the word redo, which consists of the prefix re-and the base root do.
If next year is worse than this one, I will be surprised. The morphologically past variants of future modals can be used to create a periphrastic future-in-the-past construction. [3] [4] Here the sentence as a whole refers to some particular past time, but would win refers to a time in the future
The base form or plain form of an English verb is not marked by any inflectional ending.. Certain derivational suffixes are frequently used to form verbs, such as -en (sharpen), -ate (formulate), -fy (electrify), and -ise/ize (realise/realize), but verbs with those suffixes are nonetheless considered to be base-form verbs.
