Adjective
Full of speed (in any sense).
Source: Webster's dictionaryBut notwithstanding this rightful knitting and this endless oneing, yet the redemption and the again-buying of mankind is needful and speedful in everything, as it is done for the same intent and to the same end that Holy Church in our Faith us teacheth. Julian of Norwich
He hath great ruth, and therefore He will Himself make them more open to us, whereby we may know Him and love Him and cleave to Him. For all that is speedful for us to learn and to know, full courteously will our Lord shew us. Julian of Norwich
