Question

Which one of the following is a correctly spelled word?

• A. Photographor
• B. Commissionar
• C. Astranauts
• D. Archaeologist

Hint:

Break compound words down into their active etymological segments to spot simple vowel replacements: * $\text{Astro (Star)} + \text{naut (Sailor)} = \textbf{Astronaut}$ * $\text{Archaeo (Ancient)} + \text{logist (Student of)} = \textbf{Archaeologist}$

Answer 1

The Correct Option is D

Concept: This question requires identifying the single term that is entirely free of typographical and phonetic mistakes. Agent nouns representing professions usually end with specific suffixes like -er, -or, or -ist.

Step 1: Analyze and correct option A. * "Photographor" is incorrect. Professional designations derived from verbs ending in -graph consistently take the suffix -er. * Correct Spelling: Photographer (a person who takes photographs).

Step 2: Analyze and correct option B. * "Commissionar" is incorrect. Titles representing official ranks or heads of departments take the -er ending rather than -ar. * Correct Spelling: Commissioner (a representative of supreme authority).

Step 3: Analyze and correct option C. * "Astranauts" is incorrect. The prefix meaning star or celestial body is astro-, not astra-. * Correct Spelling: Astronauts (personnel trained to travel in a spacecraft).

Step 4: Confirm correct status for option D. * "Archaeologist" is completely correct. It features the traditional diphthong -ae- in the prefix archaeo- (meaning ancient or primitive) along with the professional suffix -logist. * Meaning: A person who studies human history and prehistory through the excavation of sites and the analysis of artifacts.
