1) The word "irrational" refers to something that is not logical or reasonable. In mathematics, an irrational number is a real number that cannot be expressed as a ratio of two integers, meaning it cannot be written as a fraction. Examples of irrational numbers include π (pi) and √2 (the square root of 2).

2) The word you are looking for is "irreducible." When something is irreducible, it means that it cannot be made smaller or simplified further. This term can be used in various contexts. For example, in mathematics, an irreducible fraction is a fraction where the numerator (the top number) and the denominator (the bottom number) have no common factors that can be cancelled out. In linguistics, an irreducible minimum refers to the smallest possible unit of meaning in a language, which cannot be divided further.
