Lanai

Cambridge's entry for lanai stacks its qualifiers before it names a synonym: raised, covered, sometimes partly closed, and often made of wood, on the front or side of a building.

Read one at a time, they are loose. Raised puts the floor above the ground around it. Covered puts a roof over it. Sometimes partly closed allows sides without requiring them, so the word fits a lanai with open sides and one with some sides closed. The synonyms Cambridge gives, porch and veranda, place it in the same family of structure.

The entry says nothing about what is underfoot. A lanai floor is whatever it was built from, and the paver surfaces the company itself names are listed in the pavers section of what 239 Exteriors cleans. Whether pavers under a lanai's roof can take a sealer is a separate question, answered at can pavers under a lanai be sealed.

Cambridge's own example sentences for lanai never place the word in Florida and never call it screened.

One example has a household that cannot eat on its lanai during algae blooms; another has a storm leaving tree limbs in the streets and porches and lanais crumpled. Neither names a state, and neither mentions a screen. Using lanai for the covered outdoor room of a house in this area is trade usage, not a dictionary, statutory or code definition.

The word is also silent about pools and floors. A lanai and a pool deck are separate terms, and Cambridge's definition of lanai names no pool. Nor does the word say how a floor was built, whether its pavers are bedded in sand or adhered to concrete in a mortar set build.
