Kindling is actually a verb, as in, the act of 'kindling' a fire, even though it's also used to describe the material used to kindle a fire. Tinder is just the material.

There are two definitions, the verb and the noun.

Now there are. -ing words typically started as verbs. Eating, sleeping, etc...

This is why English is a clusterfuck, and makes no sense compared to most languages. Imagine if we called food 'eatings', that'd be weird, eh?

We can complain about English in all sorts of ways, but the fact that gerunds are distinct from infinitives is not exactly a problem.

Perhaps you are complaining that gerunds (which are already nouns) can grow extra meanings over time. But all languages do this kind of stuff.

German has exactly the "problem" you are talking about, only worse. Depending on capitalisation, "Essen/essen" can be the noun "food" or the the verb "to eat", But when used as verb, it is usally used in the sense of the English gerund "eating".
