Question

Use the appropriate suffixes (-ion and/or -tion) on the following words:
Diffuse; Abolish

• A. Diffusion; Abolition
• B. Diffusion; Abolision
• C. Diffution; Abolision
• D. Diffuion; Abolision

Answer 1

Answer: (A)

Option A is correct. Root words that end with "-se" often require the suffix `"-ion". In this case, the "e" in Diffuse is dropped and the "s" sound changed into a "sh" sound. The suffix "-tion" is the most common among words. While this is not always the case, some root words that end with "-sh" can be replaced with the suffix "-tion" where the "sh" sound is retained. Options B, C and D are incorrect as they do not follow these rules.
