\mainlanguage[english]

\starttext

We can easily use plain English for normal text, and then switch
to greek when we want; as a first try we type the lower and
upper case 26 letters of the latin alphabet and see how they come
out in greek:
\startgreek
a b c d e f g h i j k l m n o p q r s t u v w x y z

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
\stopgreek

As it can be observed, some uppercase letters have strange
outcomes; also, j gives \greek{j} and c gives the
end-of-word sigma \greek{c}; interestingly, s gives either the
normal sigma or the end-of-word one, depending on whether it's at
the of the word or not: \greek{satrapws}.

Of course we can use the various diacritical signs: accents
(\greek{`a, 'a, ~a}), breathings (\greek{<r, >w, a"}) and
subscribed iotas (\greek{a|, h|, w|}) (these last are pretty ugly in my
opinion); observe how they automatically get the correct position
with uppercase letters: (\greek{`A, 'A, ~A, <A, >A, A|}).

Can the thing be used for serious work?
