Direct answer

The Band 7 vocabulary / Band 6 coherence trap is stuffing impressive words into paragraphs that do not connect. You deploy mitigate, ramifications, and holistic while ideas jump topic to topic with no clear line. Examiners reward precise lexis only when reference chains and paragraph logic work. Fancy tokens in disjointed flow often cap both Lexical Resource and Coherence. Fix flow first, topic sentence, one idea, explicit link, then upgrade word choice inside stable sentences.

Signals you have Band 7 words, Band 6 flow

Lexis spikes Rare adjectives with simple neighbours

Linker overload Moreover/furthermore without a logical step

Topic drift New idea mid-paragraph; pronouns unclear

Vocabulary vs coherence mismatch

Trap	Why it fails
Word-list essays	Tokens correct; argument unclear
Synonym hunting	Five words for one idea; no progression
Memorised chunks	Band 9 phrase in Band 6 syntax
Long noun piles	Hard to read; weak subject–verb links

Flow-first upgrade pattern

Draft with plain verbs. One paragraph = one claim + because + example. Add one precise collocation per theme, not per sentence. Read aloud: if you cannot paraphrase the link between sentences, cohesion is still Band 6. Pair with coherence markers overuse and connected ideas without linking.

Key takeaways

Lexis points need clear paragraph logic behind them.
One linker per move beats linker lists.
Upgrade words inside stable sentences, not before flow works.
Read aloud: if ideas jump, fix cohesion before synonyms.

FAQ

Only when meaning is precise and sentences still connect, fancy words in jumpy paragraphs often cap both Lexical Resource and Coherence.

One clear linker per paragraph move beats a list of moreover/furthermore with no logical step between ideas.

Memorise collocations you can use in full sentences, not isolated tokens dropped into Band 6 syntax.
