In many languages, some adjectives are comparable – comparison of adjectives. For example, a person may be “intelligent”, but another person may be “more intelligent”, and a third person may be the “most intelligent” of the three. The word “more” here modifies the adjective “intelligent” to indicate a comparison is being made, and “most” modifies the adjective to indicate an absolute comparison (a superlative).
Three Forms of Comparison of Adjectives in English
Positive: it is an ordinary form of adjectives

Superlative: indicates that the quality or quantity is at its highest or is most intense

Notes for Irregular Comparison of Adjectives
- Far / Farther than / the Farthest

Further and Furthest also refer to distance but they may have the meaning of “additional”
“His voice carried farther than mine.”
“Further analysis of the data is needed.”
- Old / Older than / the Oldest
- Old / Elder than / the Eldest
Older and Oldest refer to persons or things;
Elder and Eldest can only be used for members of the same family

“The older generation doesn’t like pop music.”
but Elder cannot be placed before Than so Older is used:
“Henry is my elder brother; he is two years older than I.”
