I recently learnt the word もちきり. It always seems to preceeded by a word with
particle で e.g.

> 最近、あなたの噂でもちきりよ  
>  Rumours about you are a hot topic at the moment.

I can't understand why で is used. Which type of で is this?

question
grammar particle-で
Particle で before もちきり
で particle can indicate location of action, time of action, means of action.

**で particle also indicates cause of an effect.**

In this case, **hot topic** is the effect of **rumors about you**. もちきりよ is an
**effect** , and あなたの噂 is a **cause**.

Hope it helps.

answer
The word もちきり can be literally translated like "full loaded" or "loaded all
the time", that figuratively describes a topic totally occupies people's
tongues.

So, this **で** should be taken as _instrumental_ "with", as in:

> アニメ **で** 日本語を覚える _learn Japanese **with** anime_  
>  仕事 **で** 忙しい _busy **with** work_
