What is Joined?

Joined refers to a connection or linking between two or more things. While this is the official definition, sometimes joined is also used in place of conjoined and vice versa. It is one of those words which sound similar to their synonyms but still hold a different definition and meaning. 

Joined is a very commonly used word that is included in our conversations and even written works on a daily basis. It is a form of the verb and a simple past and past participle of the word Join. It is often also used in explaining the union of two or more separate things, parties, associations, etc. Not many people know that the words joined and conjoined can not always be used interchangeably and make the mistake of using them in place of one another, which often dramatically changes the meaning of a sentence.

The word joined comes from an old French word joindre; some people also claim it comes from the Latin word conjungere. Why it doesn’t matter much where the word comes from does matter that we use it in a correct reference. Understand more clearly, let’s look at some examples: He finally joined his new office; The two teams joined hands; We joined our hands for prayer, etc.

What is Conjoined?

Conjoined is a word that sounds very similar to joined and has a meaning close to join. Conjoined refers to joining two bodies or things together; it is linking or connecting with each other. It is also sometimes seen as a synonym to joined by some people, which is not entirely correct. 

It is a term often referred to as conjoined twins that means twins that have been physically connected since birth. And therefore, the world is usually used to address twins of these kinds. If we look closely, it will notice that the word conjoined comes from the word joined by adding a prefix con. The subpart ‘co’ of this prefix generally defines that the two parts being joined together are an enclosed association to one another and therefore gives equal importance to both the parts, which are not in the case of joined.

Conjoined is also regarded as a word that originated from the Latin word conjungere and the old French word conjoindre. It is a verb and a paste and past participle tense of Conjoin. For a clear understanding, here are some examples: They are blessed with conjoined twins, she beautifully conjoined the two ideas, etc.
