Sure! Let's break down the word "tenable" in a simple way.
"Tenable" is an adjective that means something is based on sound reasoning or evidence. If an idea, argument, or position is tenable, it means that it is reasonable and can be defended with good reasons.
In more complex discussions, "tenable" can be used in legal, philosophical, or technical contexts to indicate that a position is not only reasonable but also acceptable under scrutiny.
While "tenable" primarily refers to arguments or positions that are defensible, it can also imply that something is viable or sustainable in practical terms, such as a job or a living situation.
There aren't specific idioms or phrasal verbs that directly use "tenable," but you might come across phrases like "to hold a tenable position," which means to maintain a reasonable stance in a discussion.
In summary, "tenable" means something that is reasonable and can be supported with good reasons.
