- multiply:  Multiply is one of a large family of English words based on Latin multus ‘much’, a word of uncertain origin which may be related to Greek mála ‘very’ and Latin melior ‘better’. Multiply itself comes from the Latin derivative multiplicāre, formed with the element plic- ‘fold’ found also in complicated, explicit, etc, and therefore very closely parallel to the native English compound manifold.
Other members of the family include multiple , from late Latin multiplus (the -plus is a relative of the -plic- in multiplicāre); multitude , from Latin multitūdō ‘crowd’, formed with the abstract noun suffix -tūdō; and of course the host of words formed since the 16th century with the prefix multi-, including multifarious  (based on Latin -fārius ‘doing’), multilateral , multinational , multiracial , and multistorey .
