Minimal pairs are words that differ by only one sound. When it comes to minimal pairs, it is important to note that the focus is on sounds, so the spellings of the words may be different. Within the pair, the sounds that differ may occur at the beginning or the end of the words, and the difference may occur between singleton consonants or in one sound in a consonant blend. Minimal pairs can be tricky for some speakers, and this can also impact their written work. When they struggle to differentiate either the sound or pronunciation, it is more likely that this will translate to misconceptions in spelling. That being said, check the answer whose pair of words presented may not be considered minimal pairs.
