Morphemic rules describe how a morpheme changes depending on the surrounding phonemes. Which option is accurate?

• A. They determine semantics of a morpheme
• B. They specify how a morpheme's form is conditioned by phonological context
• C. They determine word order in sentences
• D. They govern stress patterns only

Answer: (B)

Morphemic rules describe how a morpheme’s form changes based on the surrounding sounds, which is a morphophonological idea. The correct sense is that these rules specify how a morpheme’s shape is conditioned by phonological context—that is, the pronunciation of the morpheme can vary depending on neighboring phonemes. For example, the plural ending in English is pronounced differently: it’s /s/ after voiceless sounds, /z/ after voiced sounds, and /ɪz/ after sibilant sounds. This shows the form of the morpheme changing to fit the phonological environment. This topic isn’t about meaning (semantics), sentence structure (word order), or stress patterns alone, which is why those other options don’t apply.
