Spelling – Identify the single misspelled word among options A–D (choose exactly one; ignore “All correct”). A) Period B) Saggest C) Famous D) Reference

Introduction / Context:
Many English words use “gg” or “g” depending on the vowel and stress patterns. “Suggest” belongs to a family where the prefix “sug-” (from sub-) assimilates before “g”, yielding the double “gg”, but the internal vowel remains “u”, not “a”.

Given Data / Assumptions:

• Period – correct.
• Saggest – intended “suggest”.
• Famous – correct.
• Reference – correct.

Concept / Approach:
“Suggest” = “sub-” (under) + “gerere/gest-” (carry). The “b” in “sub-” assimilates to “g” → “sug-”, hence “suggest”. The vowel immediately after “sug-” remains “g” followed by “gest”, not “agg-”. So “Saggest” misuses both the initial consonant and the vowel.

Step-by-Step Solution:
1) Check morphology: su(b) + gest → suggest.2) Verify vowel: the first vowel is “u” (not “a”) after the prefix assimilation.3) Confirm other options: period, famous, reference are standard dictionary forms.4) Conclude B is the sole misspelling.

Verification / Alternative check:
Compare derivatives: suggestion, suggestive; both show “sug-” + “gest-”, never “sag-”.

Why Other Options Are Wrong:

• Period: correct; “peroid” would be wrong.
• Famous: correct; “famouse”/“famus” would be wrong.
• Reference: correct; beware “referance”.

Common Pitfalls:
Letting speech rhythm suggest “sag-”; writing “referance” for “reference”. Remember “-ence” vs “-ance” families must be learned by pattern.

Final Answer:
Saggest
