What does かけまいと mean here? From what I can understand from this is probably "You aren't doing anything unreasonable right?" How does the (worry) fit in here ? I understand that Verb dictionary form + = denial/negative However this is not a dictionary form so how does is work here

> {}{} **** {}

means .

> I understand that Verb dictionary form + = denial/negative.

Your understanding is only half-correct. The verb form that can precede depends on the type of verb.

> Type I: _**Dictionary form**_ of a verb & subsidiary verb
>
> Type II: _**Imperfective form**_ of a verb & subsidiary verbs and .

is a verb, so you need to use its imperfective form to attach to it.

> " **You're not overstraining yourself, trying not to cause me to worry, are you?** "
