How Do You Spell Science?

Spelling tips for science

The word science is hard to spell for two reasons. It uses two letters to make an [ s ] sound, sc-. It is also an exception to the classic rule: I before E, except after C. In this case, the rule does not apply. 

How to spell science: First, remember that you learn science in school, another hard word to spell that also starts with sc. Second, remember that science doesn’t follow the classic “I before E except after C” rule because the i is pronounced separately from the e that follows it (resulting in a two-syllable word), instead of being pronounced together as a single vowel sound.
