containing
"Containing" is the present participle form of the verb "contain." It has a few closely related but distinct meanings, all revolving around the idea of holding, including, or keeping something within limits. Here are the most common senses.
When something has certain elements, ingredients, or information as part of it, we say it contains them. For example, a recipe contains ingredients, or a report contains data. It is about what is included, not just physically held.

When you stop something from spreading or getting worse — like a fire, a disease, or even your emotions — you are containing it. Imagine a fire spreading through a forest: firefighters work on containing it so it does not reach the next town.
