When should I use the subjunctive case?

- in wish clauses: utinam + sub, utinam ne (when -ve) + subjunctive, vellem + imperfect/pluperfect subjunctive

-indirect question (he asked what I had eaten for dinner): he asked would be indicative, I had eaten would be subjunctive

-indirect command (he ordered me to come here): he ordered would be indicative + ut (or ne if -ve) + present sub (if main verb is present or future) or imperfect sub (if main verb is past)

-purpose clause: + ut + present sub (if main verb is present or future) or imperfect sub (if main verb is past)

-result clause: + ut or ut non (if -ve) + present sub (if main verb is present) or imperfect sub (if main verb is past)

-fearing clause: timeo, metuo, paveo, vereor + ne, ne non, ut + present (if mv is present) perfect or imperfect/pluperfect subjunctive (if main verb is past)

-quamvis + subjunctive

-cum (although) + subjunctive

-dum + subjunctive
