There are a total of 374 Prepositions that have been compiled and organized in this comprehensive list. The selection includes single-word prepositions and widely accepted multi-word prepositional phrases whose first word begins with the letter, verified against major dictionaries and corpus frequency data.

Prepositions are function words that link nouns, pronouns, or phrases to other parts of a sentence. They indicate relationships of place, time, direction, cause, and manner. They range from single words (in, on, at) to multi-word phrases (because of, in front of). They play a key role in clear sentence structure for speaking, writing, and editing.

Interesting and little-known facts about Prepositions:
– The compiled list totals 374 entries, including standard forms, common multi-word phrases, and tagged regional or archaic variants.
– A small group of prepositions (for example: of, in, to, for, on, with, at) accounts for the majority of prepositional use in large English corpora.
– “Of” ranks among the most frequent words in English, appearing more often than many common nouns and verbs.
– English relies on prepositions because it lost many case endings; many other languages express the same relations with noun inflections.
– English allows preposition stranding (e.g., “Who did you speak to?”), a pattern that is uncommon in many other languages.
– New single-word prepositions are rare; most lexical change appears as multi-word phrases or extended uses of existing words.
