The idea of something being more or greater than something else (comparative) is expressed by means of a construction which can be represented by the following formula:

A Q law' B Q puS

In this formula, A and B are the two things being compared and Q is the quality which is being measured. The two Klingon words in the formula are law' be many and puS be few. Thus, it says A's Q is many, B's Q is few or A has more Q than B has or A is Q-er than B.

Any verb expressing a quality or condition may fit into the Q slot.

la' jaq law' yaS jaq puS The commander is bolder than the officer.
(la' commander, jaq be bold, yaS officer)

To express the superlative, that something is the most or the greatest of all, the noun Hoch all is used in the B position:

la' jaq law' Hoch jaq puS The commander is boldest of all.

In comparative and superlative constructions, the verb of quality (jaq be bold in the sentences above) must be said twice.

You can definitely use the law'/puS formula as part of a longer sentence. In these examples note that the non-comparative part - which I'll mark with [square brackets] - usually appears as a sort of prologue, place stamp or dependent clause to the actual comparative:

[jonlu'meH] wo'maj pop tIn law' Hoch tIn puS
Our Empire's highest bounty has been placed on his head.

[reH latlh qabDaq] qul tuj law' Hoch tuj puS
The fire is always hotter on someone else's face.

[qIbDaq SuvwI"e'] SoH Dun law' Hoch Dun puS
You would be the greatest warrior in the galaxy.

[tlhutlhmeH] HIq ngeb qaq law' bIQ qaq puS
Drinking fake ale is better than drinking water.

[noH ghoblu'DI'] yay quv law' Hoch quv puS
In war there is nothing more honorable than victory.

[tlhIngan wo' yuQmey chovlu'chugh] Qo'noS potlh law' Hoch potlh puS
The principal planet of the Klingon Empire, Qo'noS...

[DujvamDaq] tlhIngan nuH tu'lu'bogh pov law' Hoch pov puS 'ej [DujvamDaq] 'op SuvwI' tu'lu'bogh po' law' tlhIngan yo' SuvwI' law' po' puS
It [IKV Pagh] has the best weapons and some of the finest warriors in the Klingon fleet.

This last one looks complicated, but it just uses long-ish noun phrases in the A and B slots of the A Q law' B Q puS formula.
