OFF-CENTRED CROSS

2) Specifically, a cross of the Scandinavian-type that is used on a flag which is not from, or has no connection with that region – a horizontal Latin or Scandinavian-type cross.

Please note with regard to 3) that in heraldic terms an off-centred cross whose vertical arm is centred but whose horizontal arm is closer to the top of a flag may be blazoned a Latin cross throughout, or if closer to the bottom of the flag a Latin cross throughout reversed – see ‘Latin Cross’ in ‘Appendix VIII:’ (also ‘reversed 2)’ and ‘throughout’).


OFF-SET (or OFFSET) TOWARDS
The term used to describe a charge (or charges) or a stripe (or stripes) that is (or are) set towards the hoist, fly, top or base of a flag, rather than lying on its vertical or horizontal meridian – shifted towards (see also ‘centred’, (see also ‘charge’, ‘inset’, ‘meridian’ and ‘off-centred’ and ‘optical proportions’).
