@ Stardust:No matter how much they overpower a language it is almost impossible that a language won't leave its traces on the language that overpowered it, we have the example of the extinct Illyrian and Thracian languages in the Balkans which were overpowered by Slavic languages but still the Illyrian and Thracian have played a big role in the formation of the south Slavic languages, there was a Hungarian or Romanian linguist which wrote something on this subject.
Anyways, I think celtic must have had a moderate influence in the formation of the English language.
Something about my Ancestors: ( Albanians are a mix of South Illyrian Tribes and Thracians )
ILLYRIANS:Depiction in Greco-Roman ethnography
Illyrians were regarded as an bloodthirsty, unpredictable, turbulent, and warlike peoples by Greeks and Romans. They were seen as savages on the edge of their world.
It was a stereotypical view of all northern "barbarians" and could represent a fearful impression of the Illyrians and their tenacity after fighting them. Polybius (3rd century BC) writes that "the Romans had freed the Greeks from the enemies of all mankind".
According to the Romans, the Illyrians were tall and well-built. Herodianus writes that "Pannonians are tall and strong always ready for a fight and to face danger but slow witted". Of course, this could also be considered a stereotype of the Romans used for identifying barbarians. The Roman historian Livy writes:
"...the coasts of Italy destitute of harbours, and, on the right, the Illyrians, Liburnians, and Istrians, nations of savages, and noted in general for piracy, he passed on to the coasts of the Venetians"

Thracians were seen as "barbarians" by other peoples, namely the ancient Greeks and Romans. Plato in his Republic considers them, along with the Scythians, extravagant and high spirited and his Laws considers them war-like nations grouping them with Celts, Persians, Scythians, Iberians and Carthagianians. Polybius wrote of Cotys's sober and gentle character being unlike that of most Thracians. Tacitus in his Annals writes of them being wild, savage and impatient, disobedient even to their own kings.
Polyaenus and Strabo write how the Thracians broke their pacts of truce with trickery. The Thracians struck their weapons against each other before battle, in the Thracian manner, as Polyaneus testifies. Diegylis was considered one of the most bloodthirsty chieftains by Diodorus Siculus. An Athenian club for lawless youths was named after the Triballi.
The Dii were responsible for the worst atrocities of the Peloponnesian War killing every living thing, including children and the dogs in Tanagra and Mycalessos. Thracians would impale Roman heads on their spears and rhomphaias such as in the Kallinikos skirmish at 171 BC. Herodotus writes that "they sell their children and let their maidens commerce with whatever men they please".
