Explain monophthongs, diphthongs, and the three types of conjunctions with examples.

Monophthongs are pure vowel sounds that remain constant throughout their pronunciation, without any change in the tongue position or mouth shape. Example: The vowel sound in "cat" /æ/ or "bed" /ɛ/.

Diphthongs are vowel sounds that involve a glide from one vowel quality to another within the same syllable. The tongue position changes during their pronunciation. Example: The vowel sound in "boy" /ɔɪ/ or "my" /aɪ/.

The types of conjunctions are:

• Coordinating Conjunctions: These connect words, phrases, or independent clauses of equal grammatical rank. Examples: for, and, nor, but, or, yet, so.
  1. I like coffee and tea.
  2. She wanted to go, but she was too busy.
• Subordinating Conjunctions: These connect a dependent (subordinate) clause to an independent (main) clause. Examples: although, because, since, while, if, when, unless.
  1. We stayed inside because it was raining.
  2. Although it was late, they continued working.
• Correlative Conjunctions: These are pairs of conjunctions that work together to connect grammatically equal elements in a sentence. Examples: both...and, either...or, neither...nor, not only...but also, whether...or.
  1. Both John and Mary are coming to the party.
  2. You can either stay or leave.
