The word analogy itself coming from Greek words;ana- "upon, according to" and logos -"word","speech" Hence, it is a type of linguistic skills of grouping the words into their own groups.
The analogy puzzles are used to identify the relationship between a pair of words.
The format of analogies (in puzzles) are usually as followed:
