Usage of たり construction


I would like to ask what exactly the usage of たり is in this sentence. I
understand the sentence and I get that it's somehow linking the 2 things but
would appreciate some insight on it since I've hardly got a concrete
understanding of it.

> 季節によって果物はおいしくなっ **たり** 、まずくなっ **たり** する

thanks.




It describes some different things that happen to the subject depending on
time, situation, etc.

It may be easier to understand if you rephrase it as ～すること/ときもある. Your
sentence means 季節によって果物はおいしくなるときもあれば、まずくなるときもある (here, あれば is not hypothesis
or a condition, but the same as ～もあるし～もある).

たり can mention only one thing too, implying other things or something contrary
to it.

e.g.  
週末には公園に行ったりします。

This can mean:

  * I go to a park in addition to doing other activities at weekends.
  * I go to a park sometimes and don't go there at other times at weekends.
