I am not a native , so it is hard for me to find out the difference between the words with similar letters.
e.g.
- substitute : use or add in place of.
- substantiate : provide evidence to support or prove the truth of.
- substantial : of considerable importance, size, or worth.
- substance : a particular kind of matter with uniform properties.
what I really see is "word start with subs and include Ts and As".
Is there a better way to learn this kind of words ?
