Words with double consonants in the English language almost invite you to spelling mistakes. However, a list of rules and exceptions can help direct you to the correct spelling of a word. How do you spell professional?
Origin of the Word Professional
Professional was derived from Middle English profes, an adjective which refers to “having professed one’s vows.” It was derived from Late Latin professus, which is the past participle of profitri, meaning “to profess.” Professionals were individuals who ‘claimed’ their skill to others and ‘vowed’ to practice their trade to the highest standard possible.
How Do You Spell Professional?
Spelling errors can be common when you write “professional”, as a lot is going on with this word. It contains a prefix, a suffix, and a mid-section with double consonants. We understand the reason for the misspelling. However, breaking it down and applying the rule can help spell the word correctly.
Professional has 4 syllables: “Pro-fes-sion-al” with a stress on the second syllable. However, the word Professional was derived from the Middle English word “profes” which has two syllables, Pro-fes with the stress on the second syllable.
The doubling rule states that the word must have:
- More than 1 syllable
- 1 consonant in the end that follows a vowel
- The final vowel bears the primary stress.
- Then, you double up the last consonant before adding a suffix.
Apply the rule to “profes” to turn it into the root word “profession.”
- Two syllables: Pro-fes.
- Ends in the consonant “s,” which follows the vowel “e.“
- The stress is on the final vowel “e” of the stressed syllable “-fes.“
- Therefore, you double the last consonant “s” to make it “profess” before adding the suffix “-ion.”
So, it stands to be: Profess + ion + al. That is the correct spelling.
