Important Note for Website Publishers

For a competitive-exam website, it is useful to distinguish standard English definitions from words that can have multiple meanings depending on context. Always cross-check vocabulary against a recognised dictionary before presenting a disputed definition as an absolute rule.

Recommended Reference Sources

- NCERT / Government educational resources for English-language learning and vocabulary context.

- National Council of Educational Research and Training (NCERT) – official educational resources.

- For dictionary definitions, use established reference dictionaries such as Oxford English Dictionary/Oxford Learner's Dictionaries or Merriam-Webster.
