Word Pattern Analysis

This question asks us to find a hidden pattern connecting pairs of words and apply it to a new word. We need to figure out the relationship between HELIPAD and HILOPED, and between GROUND and GRUAND, then use that same logic for DELIGHT.

HELIPAD HILOPED Analysis

Let's break down the first pair, HELIPAD transforming into HILOPED:

• Identify Letters:
  • HELIPAD has consonants H, L, P, D and vowels E, I, A.
  • HILOPED has consonants H, L, P, D and vowels I, O, E.
• Consonant Position: Notice that the consonants (H, L, P, D) appear in the same positions in both words (1st, 3rd, 5th, 7th). They stay fixed.
• Vowel Transformation: The vowels change places and potentially values.
  • The 2nd letter E changes to I.
  • The 4th letter I changes to O.
  • The 6th letter A changes to E.
• Conclusion for Pair 1: The consonants remain in place, while the vowels E, I, A transform into I, O, E respectively. This gives us the vowel rule: $E \rightarrow I$, $I \rightarrow O$, $A \rightarrow E$.

GROUND GRUAND Analysis

Now let's examine the second pair, GROUND transforming into GRUAND:

• Identify Letters:
  • GROUND has consonants G, R, N, D and vowels O, U.
  • GRUAND has consonants G, R, N, D and vowels U, A.
• Consonant Position: The consonants (G, R, N, D) are in the same positions (1st, 2nd, 5th, 6th) in both words. They are fixed.
• Vowel Transformation: The vowels O and U are transformed.
  • The 3rd letter O changes to U.
  • The 4th letter U changes to A.
• Conclusion for Pair 2: The consonants stay put. The vowels O, U transform into U, A. This gives us the vowel rule: $O \rightarrow U$, $U \rightarrow A$.

Vowel Transformation Rules

Combining the observations from both pairs, we get a consistent set of rules:

• Rule 1: Consonants remain in their original positions.
• Rule 2: Vowels transform based on the following specific substitutions:
  • $E \rightarrow I$
  • $I \rightarrow O$
  • $A \rightarrow E$
  • $O \rightarrow U$
  • $U \rightarrow A$

DELIGHT Word Transformation

Let's apply these rules to the word DELIGHT:

1. Identify Components in DELIGHT:
   • Consonants are D (1st), L (3rd), G (5th), H (6th), T (7th).
   • Vowels are E (2nd), I (4th).
2. Apply Rule 1 (Consonants): The consonants D, L, G, H, T will remain in their places. The structure looks like: D _ L _ G H T.
3. Apply Rule 2 (Vowels):
   • The vowel at the 2nd position is E. According to our rule $E \rightarrow I$, it becomes I.
   • The vowel at the 4th position is I. According to our rule $I \rightarrow O$, it becomes O.
4. Construct the Result: Placing the transformed vowels (I and O) into the structure D _ L _ G H T, we get DILOGHT.

Thus, following the pattern observed in the given pairs, DELIGHT transforms into DILOGHT.
