- Lexeme: a lexeme is the essential part of a word, the fragment that gives it its meaning and makes it understandable to the speakers of a language. It is also known as a root, as it expresses the key meaning of a word.
- Word: technically, a word is a unit of language that carries meaning and consists of one or more morphemes that are linked more or less tightly together, and has a phonetic value.

- Simple lexemes: containing a single word: give, red, car.
- Complex lexemes: made of many different things or parts that are connected: package, subhuman.
- Composite/ Multi-word lexemes: made of different parts, consisting of more than one word, such as fall in love, take into account.
- Compound lexemes: can have two roots: watermelon, sunlight.
- Phrasal lexemes: have a number of common structures of which the “noun + preposition + noun”: cash on delivery.

Morphologists usually talk in quite different terms about inflection and derivation. For instance, the different inflectional formations are referred to as inflectional categories, so that we say, for instance, that English verbs have the inflectional categories 'present tense' (e.g. (he/she) walks) and 'past tense' (e.g. (he/she) walked). But for derived lexemes like walker we would not normally say that it represents a 'derivational category ('agent noun') - instead, we simply talk about derivational patterns, formations, or meanings.

- One reason for this distinction is that often inflectional categories don't have clearly identifiable meaning, but only a syntactic function. Thus, (he/she) walks and (they) walk represent two different inflectional categories ('third-person singular' and
'third-person plural'), though they hardly differ in meaning.
- Another instance of different terminology for inflection and derivation is the use of the term allomorphy. When an inflectional category is expressed by different markers (e.g. the German plural markers -en, -er, -e), linguists often say that these are different allomorphs of a single abstract plural morpheme. But, when a derivational meaning is expressed by different formal means (e.g. the English suffixes -ation, -merit, -al for action nouns, as in reform-ation, entertain-ment, arriv-al), linguists do not normally say that these are different allomorphs of a single abstract action-noun morpheme. In this case, it is not so clear whether the difference in the terminology corresponds to a difference in the phenomena.

Inflectional morphemes represent relationships between different parts of a sentence. For example, -s expresses the relationship between the verb and the third-person singular subject; -ed expresses the relationship between the time the utterance is spoken (e.g., now) and the time of the event (past). If you say “John danced,” the -ed affix places the activity before the utterance time. Inflectional morphology is closely connected to the syntax and semantics of the sentence.

Derivational meanings are much more diverse than inflectional categories. Derivational patterns commonly change the word class of the base lexeme - i.e. nouns can be derived from verbs, adjectives from nouns, and so on. For such cases, the terms denominal ('derived from a noun'), deverbal ('derived from a verb'), and deadjectival ('derived from an adjective') are in general use.

Since creating new words for new concepts is one of the chief functions of derivational morphology, and since we have a greater need for naming diverse nominal concepts, languages generally have more means for deriving nouns than for deriving verbs and adjectives (Bauer, 2002). Some common meanings with examples from various languages are listed above.

# data[].attributes.body
Languages generally have far fewer verbs than nouns, and verb-deriving patterns are less numerous and diverse. Most commonly, verbs are derived from other verbs. Denominal and deadjectival verbs are much less widespread than deverbal verbs (Bauer, 2002). Some typical examples are
given above.

Derived adjectives are even less common than derived verbs because adjectives are used more rarely than verbs, let alone nouns. Moreover, the semantic class of adjectives that are the most developed in a number of European languages, denominal relational adjectives (of the type government -» governmental), seems to be quite rare in other areas of the world. Typical examples of derived adjectives are shown above.
