Short notes about infixes:

- Infixes are morphemes that are inserted within a word, rather than at the beginning or end.
- Infixes are relatively rare in English, but are more common in other languages such as Tagalog and Malay.
- Infixes can change the meaning or grammatical function of a word, such as in Tagalog where the infix -um- is used to indicate completion of an action.
- Infixes can be difficult to identify and analyze, as they are not as easily segmented as prefixes and suffixes.
- Infixation is a type of word formation process that involves the insertion of an infix into a word to create a new form.

Infixes

- Morphemes that are inserted within the middle of other morphemes.
- Less common than prefixes and suffixes.

Types:

- Inflectional: Change the grammatical meaning of a word (e.g., "ed" in "walked").
- Derivational: Create new words with different meanings (e.g., "-al" in "regional").

Examples:

- English: "-ing" in "walking" (inflectional)
- Japanese: "-mas" in "okimasu" (formal verb ending) (inflectional)
- Tagalog: "-um-" in "kumakain" (eating) (derivational)

Position:

- Infixes are typically located between the root and the suffix.

Purpose:

- Allow for compact and efficient word formation.
- Express complex grammatical or semantic information.

Significance:

- Provide insights into the internal structure of morphemes and words.
- Contribute to the complexity and expressiveness of languages.
