Although, though, and even though
Although is used for starting a sentence in a way that makes your statement seem surprising.
• Although it was raining very hard, they went biking.
• Although she had very little money, she gave $500 to charity. •
The children played all morning, and although they were very tired, they refused to have a nap.
Though and even though
Though and although are the same. Though is more conversational.
Even though is stronger and more emphatic than though and although.

The same ideas can also be expressed using however, nevertheless or nonetheless.
• It was raining very hard, and they went biking nonetheless.
• She had very little money but nevertheless she gave $100 to charity.
