* Repetition: We have repeated letters (two 's', two 'n').
* Dictionary: We need to find words that are actually English words.
It's impossible to give an exact number of words using only those letters. Here's why:
* Computer programs: We could use a computer program to find all possible combinations of the letters and then check if those combinations are real words. This is the most accurate method, but still challenging due to the potential for enormous combinations.
* Human effort: It's very difficult to do this manually, as the number of possibilities is huge.
However, we can find some words:
* Short words: gain, stain, gainst, ants,
* Longer words: antagonism, stagnation,
To make it easier, consider these:
* Start with the most frequent letters: "s", "n", "a", "t" are the most common.
* Try different combinations: Can you arrange the letters to form different word shapes?
