OK....now here's where I fear that I'm about to expose the Orberg method to much criticism by revealing terrible ignorance about something that I should have understood long ago.
In order to assist memorisation of vocabulary I'm writing mnemonic Latin sentences into flash cards. So from this sentence from LLPSI I'm trying to remember the meaning of mereor, mereri, meritus sum: "Numquam, regina, negabo te bene meritam esse de me, nec me paenitebit tui meminisse, dum memoria mihi est, dum animam duco!'
by the mnemonic
Post multas victorias suas Caesar multas divitias meritum esse putatus est.
Does this look OK?
