Amatorial

Example Sentences:

(1) No one could’ve been more suitable for this role than he, who bubbled away his evenings in Simpson’s in the Strand or the Cafe Royal, who spent royally when he had money and borrowed regally when he didn’t, and whose contacts with the working class – with the exception of servants – were at once amatory and pecuniary.
(2) Owing partly to the attractive prettiness with which the stationery is now produced, and partly to the substitution of the natural language of affectionate congratulation for the high-flown amatory addresses of the common valentine, an increasing proportion of correspondence passing annually through the post-office on the 14th of February is addressed to children.
