English Vocabulary: Completing Words with Missing Vowels
KEY FORMULA / RULE: In English spelling exercises, words can be reconstructed from their consonant skeleton by identifying common adjective patterns, root words, and standard vowel combinations (a, e, i, o, u).
SOLUTION & WORD ANALYSIS
Each given prompt consists of the core consonants of a descriptive adjective. Inserting the appropriate vowels reconstructs the target vocabulary word:
- nvlbl \rightarrow invaluable: Formed by adding i, a, u, a, and e (i\text{n}va\text{lu}a\text{bl}e), meaning extremely useful or priceless.
- mprtnt \rightarrow important: Formed by adding i, o, and a (i\text{mp}o\text{rt}a\text{nt}), meaning of great significance or value.
- lnly \rightarrow lonely: Formed by adding o and e (\text{l}o\text{n}e\text{ly}), meaning sad because one has no friends or company.
- gnt \rightarrow giant: Formed by adding i and a (\text{g}ia\text{nt}), meaning of very great size or force.
- mzng \rightarrow amazing: Formed by adding a, a, and i (a\text{m}a\text{z}i\text{ng}), meaning causing great surprise or wonder.
- ncrdbl \rightarrow incredible: Formed by adding i, e, i, and e (i\text{ncr}e\text{d}i\text{bl}e), meaning impossible or difficult to believe.
- mpl \rightarrow ample: Formed by adding a and e (a\text{mpl}e), meaning enough or more than enough; plentiful.
- prcs \rightarrow precious: Formed by adding e, i, o, and u (\text{pr}e\text{c}iou\text{s}), meaning of great value, not to be wasted.
- sgnfcnt \rightarrow significant: Formed by adding i, i, i, and a (\text{s}i\text{gn}i\text{f}i\text{c}a\text{nt}), meaning sufficiently great or important.
- isltd \rightarrow isolated: Formed by adding o, a, and e (i\text{s}o\text{l}a\text{t}e\text{d}), meaning far away from other places, buildings, or people.
FINAL ANSWER:
- nvlbl: invaluable
- mprtnt: important
- lnly: lonely
- gnt: giant
- mzng: amazing
- ncrdbl: incredible
- mpl: ample
- prcs: precious
- sgnfcnt: significant
- isltd: isolated
EXAM INSIGHT / PITFALL: Be careful with words containing vowel clusters such as precious (-ious) and invaluable (-uable), where multiple vowels sit side-by-side between consonants.
