How do you use in this in a sentence??

Hey bartender ! I'd shore like smor ale, cause I'm on vocation.

I was proud of my vocation as a psychologist because I helped various people with negative morale.

According to m-w.com, "vocation" is a noun and can be defined as:

1 a: a summons or strong inclination to a particular state or course of action; especially : a divine call to the religious life b: an entry into the priesthood or a religious order
2 a: the work in which a person is regularly employed : occupation b: the persons engaged in a particular occupation
3: the special function of an individual or group

So one way to use the word in a sentence is to talk about someone's job or the work of an organization.

Ex:
A few years ago if anyone had told Alex that he would have enjoyed a vocation as an artist, he would have just laughed, however that was before he fell in love with painting.

As for "morale", it is a noun, and m-w.com defines it as:

1: moral principles, teachings, or conduct
2 a: the mental and emotional condition (as of enthusiasm, confidence, or loyalty) of an individual or group with regard to the function or tasks at hand b: a sense of common purpose with respect to a group : esprit de corps
3: the level of individual psychological well-being based on such factors as a sense of purpose and confidence in the future

So one way the word can be used in a sentence is to describe the emotional condition of an individual or group.

Ex:
After so many hardships out on the trail the morale of the settlers was low but they knew that if they wanted to get over the mountains before winter they would have to press on, no matter what.

His obvious lack of intelligence prevented him from occupying a respectable vocation which was a crippling blow to his morale?

All I could think of off the top of me head. Hope this helps!

You just did!
