(Auto-generated)

Press me not, beseech you, so, There is no tongue that moves, none, none i' the world, So soon as yours, could win me: so it should now, Were there necessity in your request, although 'Twere needful I denied it.†
Scene 1.2 *

although = even though -- used to connect contrasting ideas
—Behold, my lords, Although the print be little, the whole matter And copy of the father,—eye, nose, lip, The trick of his frown, his forehead; nay, the valley, The pretty dimples of his chin and cheek; his smiles; The very mould and frame of hand, nail, finger:—And thou, good goddess Nature, which hast made it So like to him that got it, if thou hast The ordering of the mind too, 'mongst all colours No yellow in't, lest she suspect, as he does, Her children not her husband's!†
Scene 2.3

Definitions:

(1) (although)
even though -- used to introduce an idea that contrasts with or makes the main statement surprising

At the start of a sentence, although can play a role similar to words like however, yet, still, even so, on the other hand, or nonetheless—all of which signal contrast. In the middle of a sentence, although can sometimes be used where but or though might also work, but though or but often sound more natural. For example, "She's a great teacher, though not the most popular" is usually smoother than "She's a great teacher, although not the most popular."
