[Grammar] Superior to / Taller than

[MMMANI52]

The horse is superior to the ox in strength.

Peter is taller than Paul

The grammar rules mention that adjectives of comparison like inferior, superior, senior, junior, etc. take the preposition ‘to’, not ‘than’. If so why it is ‘taller than’ and not ‘taller to’

 

[tedmc]

There are three degrees of adjective - positive, comparative and superlative. "Taller" is a comparative, which needs "than", whereas "superior" is a positive. The comparative of "superior" is "more superior".

 

[5jj]

• Superior already has ‘more’ as part of its meaning. ✗Don’t say: more superior
