Note 30 — PART III
Reading edition
Always use the compound tense if the simple form is likely to confuse the meaning. Note that the words jam antaŭe (already beforehand), or, simply, jam, show the action has passed, and that therefore the simple tense can be used. If these words be omitted, the compound tense must be used. The same remarks apply to the Sentences 8 and 10 (see par. 226 (a)).
