  We investigate the fundamental group of Griffiths' space, and the first
singular homology group of this space and of the Hawaiian Earring by using
(countable) reduced tame words. We prove that two such words represent the same
element in the corresponding group if and only if they can be carried to the
same tame word by a finite number of word transformations from a given list.
This enables us to construct elements with special properties in these groups.
By applying this method we prove that the two homology groups contain
uncountably many different elements that can be represented by infinite
concatenations of countably many commutators of loops. As another application
we give a short proof that these homology groups contain the direct sum of
2^{\aleph_0} copies of \mathbb{Q}. Finally, we show that the fundamental group
of Griffith's space contains \mathbb{Q}.
