At, by – Difference & usage with examples


The prepositions 'at' and 'by' are some of the most commonly used ones across the English literature. Sometimes, these words are often interchanged in sentences that convey the same meaning. Hence, it is inevitable that you will get confused on which to use where. For example, take a look at the sentences below:

1. The tourist office is located at Andheri Plaza.
2. The tourist office is located by Andheri Plaza.

Both the sentences mean the same thing, but there are subtle differences. To understand them, let's study 'at' and 'by' in detail. You will only learn English fluently if you manage to get the concepts right in detail.

use the words in right place

1. At

'At' is a preposition used in English grammar. It is used to exactly denote a place, time or activity. For example:

a. "I will be there at 1.00 pm'
b. 'There is a party at the beach house.'
c. 'There were hundreds of people at the game.'
d. 'Please send a mail at This email address is being protected from spambots. You need JavaScript enabled to view it..'

2. By

'By' is also a preposition that is used in English grammar. It is primarily used to vaguely identify a location and time. It is also used to denote specific purpose of an activity. For example:

a. The post office is by the fish market.
b. The flowers were delivered by a mailman.
c. He finally broke the record by pure effort.
d. The branch office was closed by the parent company.
e. You can pass the test by preparing well for it.

all verbs


Though both the words may be used interchangeably in many situations, their basic differences are as follows:

1. At:

a. Specific

At is used when the location or time is very specifically denoted.

b. Tangible.

At only denotes those things that are tangible and can be felt or seen.

2. By:

a. Vague

By is used to refer to vague locations or time.

b. Intangible.

It is used to refer intangible objects.

In the above main example of tourist office, 'at' Andheri Plaza means the tourist office is at the exact location of Andheri Plaza. 'By' Andheri Plaza means the tourist office is in a nearby location of the plaza.

1. The train will arrive at 1.25 pm
2. The prime minister lives at 10 Janpath.
3. You will find the shop at the end of the street.
