Which affix type connects morphemes to form a compound word?

• A. Interfixes
• B. Circumfixes
• C. Derivational affixes
• D. Inflectional affixes

Answer: (A)

The idea here is a linking piece that sits between two roots to form a single compound word. That linking element is called an interfix. It helps the two morphemes blend smoothly in speech, but it doesn’t carry independent meaning of its own. This is different from circumfixes, which wrap around a root (before and after), from derivational affixes, which create new words or change part of speech, and from inflectional affixes, which mark grammatical features like tense or number. So when a word-formation question asks which type connects two morphemes to form a compound, the connecting element being described is an interfix.
