Add ylab to ggplot with fivethirtyeight ggtheme

[Montana]

For example, could I theoretically add:

theme(axis.title = element_text()) + ylab('Something')

To my graph, but then I'll still get an x axis label. I'm thinking an alternative would be to use:

theme(axis.title = element_text(), axis.title.x = element_blank()) + ylab('Something')

Any help is appreciated.
