Honorificabilitudinitatibus is the dative and ablative plural of the medieval Latin word honōrificābilitūdinitās, which can be translated as "the state of being able to achieve honours". It is mentioned by the character Costard in Act V, Scene I of William Shakespeare's Love's Labour's Lost.

Guaiacum, sometimes spelled Guajacum, is a genus of flowering plants in the caltrop family Zygophyllaceae. It contains five species of slow-growing shrubs and trees, reaching a height of approximately 20 m (66 ft) but usually less than half of that. All are native to subtropical and tropical regions of the Americas and are commonly known as lignum-vitae, guayacán (Spanish), or gaïac (French). The genus name originated in Taíno, the language spoken by the native Taínos of the Bahamas; it was adopted into English in 1533, the first word in that language of American origin.
