The Grammar Transformer

Choose a function. A connector. A position.

Four semantic functions, three connectors each, two positions — 24 combinations. Buttons A, B, C reveal a different connector word. Watch how the punctuation shifts when position changes.

The proposal impressed the investors. However, the committee rejected it.
Pattern:connector + comma — begins a new sentence
Contrast connectors signal an opposing or unexpected idea. "However" is the most common at B2+. "On the other hand" typically introduces the second side of a two-sided argument. "Nevertheless" is slightly more formal.

Four functions, twelve connectors

Every connector belongs to a semantic category. Choose the right function first, then pick the appropriate word for the register.

Addition

“and here is another point”
  • furthermore formal, academic
  • moreover formal, adds weight
  • in addition neutral, versatile

Contrast

“but consider this opposing idea”
  • however most common at B2+
  • nevertheless more formal
  • on the other hand two-sided argument

Result

“this happened because of that”
  • therefore formal, logical
  • consequently formal, cause-effect
  • as a result neutral, versatile

Concession

“yes, but despite that...”
  • nonetheless formal, strong
  • even so slightly informal
  • that said conversational, B2+

Position changes the punctuation

Conjunctive adverbs can move. Where you place them affects the commas around them.

Sentence-initial

Connector + comma + main clause.

However, the plan was not approved.

Therefore, we had to find a new supplier.

Furthermore, costs were rising rapidly.

A new sentence begins. Capital letter + connector + comma.

Mid-sentence (parenthetical)

Subject + comma + connector + comma + predicate.

The plan, however, was not approved.

Costs were, therefore, rising rapidly.

The team, nonetheless, delivered on time.

The connector is bracketed by commas on both sides.

Same idea — different connector, different grammar

Conjunctive adverb

Sales fell. However, we met our targets.

Subordinating conjunction

Although sales fell, we met our targets.

Conjunctive adverb

Costs rose. Therefore, we cut the budget.

Subordinating conjunction

Because costs rose, we cut the budget.

Conjunctive adverb

It was late. Nevertheless, she continued working.

Preposition

Despite the late hour, she continued working.

Register note

Conjunctive adverbs (however, therefore, furthermore) are the backbone of formal written English — essays, reports, academic writing, business emails. In conversation, prefer simpler words: but, so, also, still. Using “however” in casual speech sounds over-formal.

The rules to remember

Choose your connector by function first: addition (furthermore / moreover / in addition), contrast (however / nevertheless / on the other hand), result (therefore / consequently / as a result), concession (nonetheless / even so / that said). Then check the position: sentence-initial needs a comma after; mid-sentence needs commas on both sides. In formal writing, always prefer these over but, so, or also.
