An affix is a morpheme added to a word stem to form a new word or word form. Affixes can change the meaning or grammatical function of a word.

Identifying Types of Affixes

The question asks to identify the types of affixes among the given options. Let's analyze each option:

• Infix: This is a type of affix inserted *within* the base form of a word. For example, in some languages, an infix might be added to the middle of a root word.
• Circumfix: This consists of two parts, one placed at the beginning (prefix) and the other at the end (suffix) of a word stem, working together as a single unit. For example, German uses circumfixes like ge-...-t in past participles (e.g., gesagt from sagen).
• Transfix: This type of affix involves breaking up the root morpheme and inserting discontinuous elements into it. It is common in Semitic languages, like Arabic, where root consonants are interspersed with vowels and other morphemes to form different words (e.g., the root K-T-B relates to writing, forming words like kataba 'he wrote' and kitab 'book').
• Graphfix: This is not a recognized linguistic term for a type of affix. It might relate to graphemes (written symbols) but does not describe a morphological process of affixation.

Conclusion on Affix Types

Based on linguistic definitions, Infix, Circumfix, and Transfix are established types of affixes. Graphfix is not.

Therefore, the correct options representing types of affixes are Infix, Circumfix, and Transfix.
