The Trap: Single-syllable words like "irf" carry primary acoustic prominence in isolation, but can be swallowed in rapid connected speech.
How Native Speakers Say It: Sustain vowel clarity without rushing into the trailing consonant. Elevate pitch slightly when "irf" carries the primary contrast or new information in a sentence.
Connected Speech & Natural Conversational Flow
When "irf" is followed by a word starting with a vowel, glide the final consonant into the opening vowel (e.g. "irf is" sounds like "irf-iz").
