How do you spell...

Take note of the spelling of these words...
1. Conscious (many would leave out letter C after letter S)
2. Passers-by (not passer-bys)
3. Stretcher (do not leave out letter T. Spell 'stretch' and add suffix 'er')
4. In front (two words, not one)
5. Forward (not foward)
6. Immediately (don't forget letter E before the suffix 'ly')
7. Replied (not repiled, the root form is reply. Hence 'replies, replied)
8. Jogged past (not jogged passed. Past is a preposition. Passed is the past tense for pass.)
