Equus = Horse Caballus = Horse, but an inferior one - a nag.
You probably mean Semper vigilo, which is Latin for "I am always vigilant".
Semper = Always Vinco = Victorious
it means horse
Do you mean "Semper Fi"?"Semper Fi" is short for "Semper Fidelis", and that is Latin for "Always Faithful".Semper Fidelis is Latin for "Always Faithful". It is the motto of the United States Marine Corps.
Semper Fi is short for Semper Fidelis which means Always Faithful. Semper Paratus means Always Prepared.

vester semper is non grammatic Latin for "always yours"
"Semper tua" and "Semper tuus" both mean "Always yours". Difference is in sex of person who writes this state. "Semper tua" writes woman. "Semper tuus" writes man. But neither really means 'always yours' - that would be Semper tibi - for both genders.
