Common Pronunciation Traps & Learner Mistakes
The Trap: Pronouncing a hard, aspirated [tʰ] in casual conversation can sound overly formal in North America.
How Native Speakers Say It: In American English, a single "t" between vowels quickly taps against the alveolar ridge like a soft "d" ([ɾ]). In British English, maintain a crisp aspirated [tʰ].
Connected Speech & Natural Conversational Flow
When "infinitesimally" is followed by a word starting with a vowel, glide the final consonant into the opening vowel (e.g. "infinitesimally is" sounds like "infinitesimally-iz").
Maintain the stress-timed rhythm of English: compress unstressed syllables rapidly so the beat of "infinitesimally" aligns naturally with adjacent words.
