There are over 600 adjectives in the English language that end in -inal. What does this suffix mean? The -inal suffix after a root word means “relating to.” For example, medicinal means “relating to medicine.” The tricky part is that some -inal words often get long (one of them is 23 letters long!) because they are latinate (of Latin origin). Long words are often the trickiest to pronounce, right? Let’s take a look at a rule that will help you out next time you have to pronounce a word that ends in -inal.
Rules on how to pronounce –inal words:
- Place the syllable stress on the syllable just before the -inal combination.
- To pronounce these words naturally, you should also pronounce the “i” and “a” as schwas. Both vowels take on a schwa sound because they’re not stressed. For example, abdominal sounds like /ahb-DOM-uh-nuhl/
Examples to practice with:
Here is a list of some common words that end in -inal. Practice saying them out loud, following the 2 guidelines above. Then, listen to the audio to compare your pronunciation to that of a native speaker.
