(sentence), though

"Though" is similar to "but" and "however". It is usually used at the end of the sentence in spoken English:

I have a pilot's license. I haven't flown in almost 5 years, though.

In written English, it's more appropriate to use it between clauses:

I have a pilot's license, though I haven't flown in almost 5 years.

"However" can be used in the same way:

I do agree with the Prime Minister on defense, however.

"Though" is more casual than "however", though.

(someone) drives recklessly

"Reckless driving" is a phrase that means driving very unsafely. A reckless driver might do things like:

• drive way too fast
• drive while typing a text message
• drive through a stoplight that's turned red already

You can get a ticket for "reckless driving" if the police catch you doing something dangerous.

You can also say that a person is "reckless" if they do lots of dangerous things, whether in a car or somewhere else:

He was always reckless: drinking, getting into fights, gambling. It's sad what happened to him, but we all saw it coming.

(someone) is accident-prone

When someone tends to have a lot of accidents, you can describe them as "accident-prone":

Yolanda? She's very accident-prone. She's always bumping into things, dropping things, you name it.

Being "accident-prone" is a little different from being "clumsy". A "clumsy" person isn't very good at moving their body.

I could never be a dancer. Way too clumsy.

Someone who is "accident-prone" could have a lot of accidents because they're clumsy, or it could be because they're not careful. Or it could just be bad luck.
