In grammar
Grammar
In linguistics, grammar is the set of structural rules that govern the composition of clauses, phrases, and words in any given natural language. The term refers also to the study of such rules, and this field includes morphology, syntax, and phonology, often complemented by phonetics, semantics,...

Structure

The structure of a comparative in English consists normally of the positive
Positive (linguistics)
Positive is the form of an adjective or adverb on which comparative and superlative are formed, in English, with the suffixes -ier, -lier, -iest, or -liest, or the forms more/less for polysyllabic adjectives/adverbs. In English, good is a positive adjectival form corresponding to the comparative...

Affix
An affix is a morpheme that is attached to a word stem to form a new word. Affixes may be derivational, like English -ness and pre-, or inflectional, like English plural -s and past tense -ed. They are bound morphemes by definition; prefixes and suffixes may be separable affixes...

 which is being compared, e.g. "He is taller than his father", or "The village is less picturesque than the town nearby". Than is used as a subordinating conjunction to introduce the second element of a comparative sentence while the first element expresses the difference, as in "Our new house is larger than the old one", "There is less water in Saudi Arabia

."

Some adjectives and adverbs that deal with the concept of distance use the modifiers further and furthest (or farther and farthest) instead of more, for example, "The boy ran further away" or "The expedition was the furthest up the river ever recorded".

Two-clause sentences

For sentences with the two clauses other two-part comparative subordinating conjunctions may be used:
  1. as...as   "The house was as large as two put together."
  2. not so / not as ...as   "The coat of paint is not as [not so] fresh as it used to be."
  3. the same ... as   "This car is the same size as the old one."
  4. less / more ... than   "It cost me more to rent than I had hoped."

Adverbs

In English, adverbs are usually formed by adding -ly to the end of an adjective. In the comparative, more (or less) is added before the adverb, as in "This sofa seats three people more comfortably than the other one." Some irregular adverbs such as fast or hard do not use more, but add an -er suffix, as the adjectives do. Thus: "My new car starts faster than the old one" or "She studies harder than her sister does."

For some one-syllable adjectives, the comparative of adjectives may be used interchangeably with the comparative of adverbs, with no change in meaning: "My new car starts more quickly than the old one" or "My new car starts quicker than the old one".

However, if the adjective has an irregular comparative, then the adverb must use it: "She writes better than I do" or "He threw the ball farther than his brother did."

Null comparative

The null comparative is a comparative in which the starting point for comparison

In some cases it is easy to infer what the missing element in a null comparative is. In other cases the speaker or writer has been deliberately vague in this regard, for example "Glasgow's miles better
Glasgow's miles better

Greater/lesser

Scientific classification, taxonomy and geographical categorization conventionally include the adjectives greater and lesser, when a large or small variety of an item is meant, as in the greater celandine

 as opposed to the lesser celandine
Lesser celandine
Lesser celandine is a low-growing, hairless perennial plant, with fleshy dark green, heart-shaped leaves. The plant is found throughout Europe and west Asia and is now introduced in North America. It prefers bare, damp ground and in the UK it is often a persistent garden weed...

. These adjectives may at first sight appear as a kind of null comparative, when as is usual, they are cited without their opposite counterpart. It is clear however, when reference literature is consulted that an entirely different variety of animal, scientific or geographical object is intended. Thus it may be found, for example, that the lesser panda entails a giant panda
Giant Panda
The giant panda, or panda is a bear native to central-western and south western China. It is easily recognized by its large, distinctive black patches around the eyes, over the ears, and across its round body. Though it belongs to the order Carnivora, the panda's diet is 99% bamboo...

.

It is in the nature of grammatical conventions evolving over time that it is difficult to establish when they first became widely accepted, but both greater and lesser in these instances have over time become mere adjectives (or adverbial constructs), so losing their comparative connotation.
