Connector Words and English Register
Reference material on conjunctions, connectors, and formal-informal register in English.
Concession connectors
- Although / Though — Interchangeable in most sentences; 'though' can also end a sentence informally, 'although' cannot.
- Even though — Stronger emphasis on contrast than though/although; never shortened to 'even tho' in formal writing.
- Despite / In spite of — Followed by a noun or -ing form, not a full clause: 'despite the rain', not 'despite it rained'.
- Nevertheless / Nonetheless — Formal sentence-starters showing contrast with the previous sentence.
Register and spelling
- Tho, thru, cuz — Informal shortened spellings common in texting and social media, not accepted in academic writing.
- Gonna, wanna, gotta — Informal contractions of going to, want to, got to; avoid in formal emails and essays.
- Contractions in formal writing — Most style guides discourage don't and can't in academic papers; spell out in full.
Common mistakes
- But after although — Avoid pairing: 'Although it rained, but we went out' - use one connector, not both.
- Comma placement — Use a comma after an introductory clause: 'Although it rained, we went out.'
- Though vs through vs thorough — Frequently confused spellings with different meanings and pronunciations.
