What are the five pairs of consonants?

There's a bit of a misunderstanding here. The term "pairs of consonants" isn't a standard linguistic concept. It's more common to talk about pairs of sounds, which can be consonants or vowels.

Here are some common pairs of sounds in English:

* Minimal pairs: These are words that differ by only one sound, and the difference in sound changes the meaning of the word. Examples include:

* bat vs. pat

* dog vs. tog (although "tog" isn't a common word)

* man vs. nan (again, "nan" isn't common)

* fat vs. vat

* sun vs. zun (although "zun" isn't a common word)

* Allophones: These are different pronunciations of the same sound, which don't change the meaning of the word. For example, the "t" sound at the beginning of "top" is different from the "t" sound at the end of "pot".

* Complementary Distribution: This refers to sounds that never appear in the same environment. For example, the aspirated "t" sound (like in "top") only occurs at the beginning of a word, while the unaspirated "t" sound (like in "pot") only occurs at the end of a word.
