ん (Slang)Slang abbreviation

Being the shortest sound in the Japanese language, ん is often used for abbreviation, especially in casual speech. Abbreviation with ん occurs primarily for the purpose of making part (A) and part (B) of a statement flow together more smoothly.

In general, ん will only replace sounds that require rolling of the tongue. Thankfully, this will be easy to remember, as it is just the ら, り, る, れ, ろ sounds.

The first common way that this ん is used is for replacing the ら negative stem in verbs where る changes to ら. Actually, even if something is not a verb, if it contains らない, it can be shortened in this way. An example of this can be seen in the い-Adjective つまらない, 'boring'.

The second pattern where ん will be used is when it not only replaces る, but replaces the entire いる 'to be' in the ている progressive form of verbs.

One thing that you will notice is that regardless of whether ん abbreviates らない or ている, there is always something following the ん. This will be important to learn, as this type of 'lazy' abbreviation will not have a sentence end with ん. We can remember this by remembering that the goal is to make (A) and (B) flow together, so if there is no (B), there is no need for ん.
