Even though most of us don't use horses or buggies as our main transportation these days, our language still has horse-related idioms, which writers sometimes mix up.

When we speak of a group or a team coming together to form a cohesive whole or when we write about an idea becoming a concrete plan of action, we usually use the spelling jell for the verb. However, gel can also mean something has taken definite form.

I like to reserve gel, though, for congeled, as when a gelatin sets. The dessert gelled; the plans jelled.

A brooch is a piece of jewelry. It has a pin and a clasp so that it can be attached to clothing. The word is pronounced "broch," with a long o, and that leads to a common misspelling: broach.

A broach is a rod used for roasting meat or a sharp-pointed tool used for making a hole. The verb broach means to make a hole, as in a cask, or to open a discussion or bring up a subject.

Some dictionaries list broach as an alternate spelling for brooch, by the way, but most usage experts still separate the two spellings.

Both broach and brooch come from Middle English broche for a pin, peg or spit.
