Ligatures
Ancient Armenian manuscripts used many ligatures to save space. Some of the commonly used ligatures are: ﬓ (մ+ն), ﬔ (մ+ե), ﬕ (մ+ի), ﬖ (վ+ն), ﬗ (մ+խ), և (ե+ւ), etc. After the invention of printing Armenian typefaces made a wide use of ligatures as well. In the new orthography the character և is no longer a typographical ligature, but a distinct letter with a place in the new alphabetic sequence, before "o".
