While English has borrowed much vocabulary from non-Germanic languages, it remains a Germanic language in its core structure and sounds. English shares phonological innovations with other Germanic languages that differentiate it from other Indo-European families. The morphology of English also differs from other Indo-European languages in its verb systems, voices, moods and tenses. English is most closely related to the West Germanic Anglo-Frisian subdivision.

1. ENGLISH AS A GERMANIC LANGUAGE
 English has borrowed much vocabulary from non-
Germanic languages.
 -It remains a Germanic language not only in its
core but also in its sounds and structure.

2.  1822 – Jacob Grimm demonstrated a general
phonological difference between the Germanic
family of languages and the other Indo-European
languages.
 Some sounds in the Indo-European languages
correspond to some sounds of the Germanic
languages. (result of a phonological change)

3.  English shares with the other Germanic languages
a number of phonological innovations that can
differentiate it from the rest of the Indo-European
family.
 Prosodic changes had more profound effects in
Proto-Germanic, however those regularities are
less observables in Present-day English.

4. MORPHOLOGY
 The morphology of English and its Germanic
relatives also differs from the other Indo-European
languages in the verbs systems, voices, moods and
tenses.
 For the order of elements, in English have
subsequently become fixed in the language in the
pattern subject-verb-object (SVO) but in the
Present-day English there survive relics of the older
system.

5.  The differences between the Germanic languages
and the rest of the Indo-European group are fairly
striking. There are regular differences among the
Germanic languages themselves.
 The family can be sectioned into three
subdivisions; East, North and West Germanic.
 There are some resemblances among these three
subdivisions as well as some chronological differences.
The most relevant group is probably the West
Germanic, which has three subdivisions; Anglo-Frisian,
Low German and High German.

6.  From these three, the Anglo Frisian is the most
closely related to Present-day English.
