While historically a verb (short for 'if it please you'), in modern grammar 'please' in this context is often categorized as a politeness marker or adverb.

'Broken' is placed directly before the noun it modifies ('window'). This position is called 'attributive'.

'Unless' introduces a dependent condition clause, making it a subordinating conjunction.

Here, 'outside' is preceded by 'The' and functions as the subject/object itself. It is a noun.

Verbs ending in -ing that function as nouns (subjects or objects) are Gerunds.

The word 'to' when placed before a verb base (e.g., 'to run') acts as an infinitive marker, not a preposition.

'Somewhat' modifies the adjective 'tired', indicating degree. It is an adverb.

'Dark' describes the nature or characteristic of the night. It is an adjective of quality.

'Bravery' refers to a quality or concept, not a physical object. It is an abstract noun.

'Nearer' is the comparative form of the adverb 'near', modifying 'Come'.
