Connect vs. Attach
'Connect' and 'attach' are synonyms but they differ in the direction of the action they indicate and are also grammatically different.
Both 'connect' and 'attach' mean to link or join two or more things. However, 'connect' is a reciprocal verb that indicates two objects are mutually joined while 'attach' implies that a secondary object is joined to a more important object. Follow the lesson to find out how the two verbs differ in their scope of usage.
Direction of Action
'Connect' is a reciprocal verb, which means that two objects that 'connect' to each other are of equal value, size, etc. and the act of connecting is mutually performed or received between them. 'Attach' on the other hand, indicates a one-sided relationship where one object that is smaller or less important is joined or fastened to a bigger or more important object. For example:
I
The train station
Here, the city and the neighboring towns are mutually connected in a two-sided relationship.
Please
Here, the receipt is a secondary object that is attached to a main object. You cannot use 'connect' in this sentences.
The carpenter
Grammatical Difference
'Connect' can be both a transitive and an intransitive verb. As such, it can describe different types of links between objects, for example, two or more things can connect to each other (intransitive), or one thing can be connected to another, sometimes through an intervening object such as a door, bridge, road, cable, etc. 'Attach', on the other hand, is always transitive and means to join or fasten one thing to another, for example using a glue, rope, etc. Here are some examples:
