Fine-Grained Conditionals: dès que, pourvu que, à condition que, au cas où
நுணுக்கமான நிபந்தனை இணைப்புச் சொற்கள்
Four conjunctions look similar on the surface — all translate loosely as 'as soon as / provided that / on condition that / in case' — but each locks in a different mood and a different degree of certainty, so mixing them up changes what you're actually claiming.
Grammar Comparison
இலக்கண ஒப்பீடு
dès que: indicative, and often futur when future-facing
Dès que tu arriveras, appelle-moi. (As soon as you arrive, call me.)
நீ வந்த உடனே, என்னைக் கூப்பிடு.
dès que ('as soon as') takes the indicative, not the subjunctive — and when the event it describes is future, both clauses typically go into the futur simple in French (dès que tu arriveras...), unlike English, which uses a present tense in the 'as soon as' clause ('as soon as you arrive'). Forgetting the futur here, and defaulting to présent the way English does, is one of the most common tense-agreement slips at this level.
pourvu que and à condition que: both trigger subjonctif
Pourvu qu'il fasse beau demain ! (I hope it's nice weather tomorrow! / Provided it's nice tomorrow!) / Tu peux sortir, à condition que tu rentres avant minuit. (You can go out, on condition that you're back before midnight.)
நாளைக்கு நல்ல வானிலை இருந்தா சரி! / நீ வெளியே போகலாம், நள்ளிரவுக்குள் திரும்பி வந்தா!
Both introduce a condition and both require the subjunctive in the clause they govern. pourvu que has a distinctive double life: as a subordinate conjunction it means 'provided that,' but used alone at the start of an exclamation, it becomes a hopeful wish — Pourvu qu'il fasse beau ! ('Let's hope the weather's nice!'). à condition que is more neutral and contractual-sounding, common in negotiations and rules ('you may, provided that...').
au cas où: the exception — it takes the conditionnel, not the subjunctive
Prends un parapluie, au cas où il pleuvrait. (Take an umbrella, in case it rains.)
மழை பெய்யலாம், ஒரு குடையை எடுத்துக்கோ.
Despite looking like it belongs in the same 'trigger the subjunctive' family as pourvu que and à condition que, au cas où is the odd one out — it's followed by the conditionnel, never the subjunctive. This is a pure memorization point with no logical shortcut: au cas où + conditionnel is simply the fixed pattern, and reaching for a subjonctif here (a very natural mistake, given the other three conjunctions on this page) is the single most predictable error at this level.
