Conjunctions

How conjunctions connect clauses and ideas in Spanish, English and Chinese.

Compare languages

English and Spanish share many Latinate conjunctions. Chinese uses a smaller set of core conjunctions, often omitting them when context is clear. Spanish requires subjunctive after certain conjunctions of doubt or condition.

Key Takeaways

Spanish: Distinguishes pero from sino. Several conjunctions trigger the subjunctive. Uses e and u before words starting with i and o respectively.

English: Allows sentence-initial conjunctions freely. Uses the same conjunctions for coordination and subordination. Phrasal conjunctions are common.

Chinese: Has a smaller inventory. Often omits conjunctions when context makes the relationship clear. Uses paired structures (虽suī然rán...但dàn是shì, 因yīny.

Key concepts compared: And, But, Or.

Frequently Asked Questions

Why does Spanish change y to e and o to u in certain contexts?
Spanish avoids the sequence /ji/ and /wo/ for phonetic clarity: *padre e hijo* (father and son), not *padre y hijo*; *siete u ocho* (seven or eight), not *siete y ocho*. This is a purely phonological rule with no semantic content. English and Chinese have no equivalent euphony rules for conjunctions. English learners of Spanish forget this rule because their conjunctions are invariant.
How does Chinese express logical relationships without relying heavily on conjunctions?
Chinese often omits conjunctions when the relationship is clear from context: '<ruby>他<rt>tā</rt></ruby><ruby>来<rt>lái</rt></ruby>,<ruby>我<rt>wǒ</rt></ruby><ruby>走<rt>zǒu</rt></ruby>' (He came, I left) implies contrast or sequence without 'but' or 'then.' Spanish and English require explicit conjunctions or adverbs in formal writing. This creates a stylistic gap: Chinese prose can feel choppy to English readers, and English prose can feel redundant to Chinese readers.
Which Spanish conjunctions require the subjunctive, and why?
Conjunctions of purpose, condition, and concession trigger the subjunctive: *para que* (so that), *a menos que* (unless), *aunque* (although). The subjunctive signals that the clause is not asserted as fact. English uses the indicative in these contexts: 'I will wait until he comes' (indicative). Spanish requires *Esperaré hasta que venga* (subjunctive). This is one of the hardest patterns for English and Chinese speakers because neither language uses mood this way.
