Spelling – Identify the single misspelled word among options A–D (choose exactly one; ignore “All correct”). A) Psychologist B) Psychaitrist C) Physiologist D) Psychoanalyst

Introduction / Context:Medical/para-medical titles share the Greek root “psyche” (mind). The physician specializing in psychiatry is a “psychiatrist”. Misspellings often insert an extra “a” after “ch” or swap vowel order, creating forms like “psychaitrist”.

Given Data / Assumptions:

• Psychologist – correct: specialist in psychology.
• Psychaitrist – intended “psychiatrist”.
• Physiologist – correct: specialist in physiology.
• Psychoanalyst – correct: practitioner of psychoanalysis.

Concept / Approach:The correct sequence is “psy-chi-a-trist”: “psychiatry” + “-ist”. Note the “ia” cluster after “chi”. Any rearrangement like “cha” or “ai” directly signals a misspelling.

Step-by-Step Solution:1) Write the base: psychiatry.2) Add suffix: psychiatry → psychiatrist (drop final “y”, add “-ist”).3) Compare with option B: “psychaitrist” misorders vowels (“ai” vs “ia”).4) Confirm A, C, D as standard professional titles.

Verification / Alternative check:Look at related term: psychiatric (psyc-hi-a-tric); the “ia” stays together in all derivatives.

Why Other Options Are Wrong:

• Psychologist: correct; “physchologist” would be wrong.
• Physiologist: correct; beware “phycologist” (which would be a different field: phycology = algae).
• Psychoanalyst: correct.

Common Pitfalls:Confusing “psych” clusters; mixing “psychiatrist” (medical doctor) with “psychologist” (not necessarily an MD).

Final Answer:Psychaitrist
