By is a preposition that names the doer of an action, the method behind it, or the moment a job must be finished, as in the fence was painted by my brother. Most sentences with by fall into one of those three duties, and the doer sentences come first.
What Is the Preposition By?
By names whoever or whatever performs an action, the means used to perform it, and the limit of a stretch of time, so one short word answers who, how, and when. With marks the tool in the hand rather than the doer, which is why a form is signed by a clerk with a blue pen.
Doer: Passive verb + by + person / Method: By + noun or by + verb-ing / Deadline: By + time

FAQs
The preposition by is used for three jobs before anything else: it names the doer after a passive verb, the method behind an action, and the deadline an action must meet. A wall painted by a neighbour, a bill paid by card, and an essay due by Friday show the three in that order. Position and measurement follow close behind, as in wait by the gate and paid by the hour.
By and until both name a moment in time, yet they treat that moment differently. By sets the latest time for one completed action, as in send the invoice by Friday, while until stretches a continuing situation up to that moment, as in the office stays open until five. Learners who want more deadline practice find it in prepositions of time example sentences.
By marks the person or force that performs an action, while with marks the tool held during it, so a letter is written by Nour with a fountain pen. Swapping the two produces written with Nour, which turns a writer into a pen. Tool sentences of every kind are gathered in sentences with with.
No, by works far outside passive sentences, even though the doer use is the most famous one. The same preposition gives transport in she goes by ferry, method in pay by card, position in wait by the gate, a deadline in finish by noon, and a rate in paid by the hour.
By is followed by a verb only in the -ing form, which turns that verb into the method of an action. Yusuf saved money by cycling to work, and Amelia improved her accent by listening to the radio. A plain infinitive after by, as in by cycle to work, is wrong in English.
By works as both, and its position in the sentence decides which. Before a noun it is a preposition, as in she sat by the window. With no noun after it, by turns into an adverb, as in a car drove by or summer went by quickly.
By counts as three different types of preposition at the same time. It marks place in by the river, time in by Thursday, and agent or means in signed by the mayor. Englishan sets out the whole family in types of prepositions, and further practice waits in parts of speech example sentences.
By and buy sound identical in speech and share nothing else at all. By is a preposition, as in the door was opened by a porter, while buy is a verb meaning to pay money for something, as in buy the tickets online before the price rises. A spellchecker never catches the swap, so learners proofread the two words themselves.
Starting a sentence with by is correct and frequent in English, most of all before a time phrase or an -ing method. By Friday the roof was finished, By the time we arrived, dinner was cold, and By reading aloud, Sara fixed her accent each open with this preposition and need a comma before the main clause.
No, position is one use out of many, and by means at the side of only when a place follows it. Wait by the door puts two objects side by side, while paid by the hour, sent by email, and written by George Orwell have nothing to do with distance.
By the time introduces a whole clause rather than a single noun, and the action in the other clause finishes first. By the time we reached the station, the last train had gone pairs a past perfect verb with a past tense verb. The same phrase looks forward in By the time you read this, I will be in Seville.
Abide by means to obey a rule or keep a promise, and the preposition never drops away: every player must abide by the referee’s decision. Other verbs demand by in the same fixed way, among them stand by a friend, go by the rules, and swear by a remedy.
