Answer:
1. A discovery is recognizing something that already exists for the first time, that nobody has found before, e.g. how Christopher Columbus discovered the Americas. An invention is creating something totally new with one's own ideas and development.
2. A principle is a rule, a law, a guideline, or a fact. A principal is the headmaster of a school or a person who's in charge of certain things in a company. Principal is also an adjective that means original, first, or most important.
3. Stationary is an adjective described to use a person, object or situation that isn't moving or changing, while stationery is a noun used to describe a collection of office items such as envelopes, papers and cards.
4. swimming is the process in which we voluntarily move our hands and legs to go through water whereas floating is the process through which we do not do anything other than floating above the water without drowning.
5. A suggestion is an idea someone proposes. You can accept or reject a suggestion. When someone gives an order — like in the military — it has to be carried out. On the other hand, a suggestion is an idea that's optional.
6. To clean means to wash something. For example, I cleaned the car, or, I cleaned the cat. To clear means to remove something from a place that is not wanted. If someone said they cleaned the table, it would usually mean that they have washed the table (as in, washed it with soap and water).
