|DOMUS (f)||HOME, HOUSE||domestic|
also connected with 'dominus'; beware 2nd decl. case endings for certain meanings
|EXERCITUS||ARMY||exercise||armies have to go on 'exercises' to train for battle|
|MANUS (f)||HAND, BAND||manual||it means a hand, or a handful; hence the idea of a small group of people|
|PORTUS||HARBOUR||port||do not confuse this with either 'porto' - I carry, or 'porta' - a gate! The '-u-' case endings are the best way to tell it apart.|
WHEN, SINCE, ALTHOUGH
Try the meanings in the order given until one makes sense ('although' is very unlikely!); to remember them: 'I thought 'cum' meant 'with'! Since When does it have Althoughs other meanings?!'
