Developing a vocabulary size
test
in Greek as a foreign
language

Vocabulary




the core component of all the language skills
(Long and Richards, 2007, xii)
without grammar very little can be conveyed,
without vocabulary nothing can be conveyed
(Wilkins, 1972, 111)
But formal tools to model and measure
vocabulary knowledge are very recent
and mainly restricted to EFL
Vocabulary Size Estimates
tend to…

Sample of the most frequent vocabulary





the most frequent vocabulary tends (but only tends) to be
learned earliest (Alexiou & Konstantakis, forthcoming)
the most frequent vocabulary gives greatest coverage (and
comprehension)
textbook neutral (unless they are very odd)
give reliable, believable estimates of a learner’s knowledge
But

underestimate
Please look at these words. Some of these words are real
French words and some are invented but are made to look like
real words. Please tick the words that you know or can use.
Here is an example.

To give us a workable frequency list
to draw items from…


proper names and other named entities stripped out
corpus is lemmatised



common inflections work differently in English and in Greek
But this process brings the corpus into line with the English and
French corpora and makes them more similar
most frequent 5000 words taken as the basis of a test
equivalent to the EFL and French tests shown


20 words from each 1000 word frequency band

Objectives
To examine:
 whether the test is reliable
 whether the frequency effects observable in
other language can be seen in Greek
 whether the frequency profile changes with
level and knowledge in the expected manner
 whether the test differentiates between
learners of different levels in predictable ways
(and suggests vocabulary knowledge required
for each CEFR level)
Reliability: An individual’s scores

Conclusions



This frequency based vocabulary size test in
Greek as a foreign language is very workable
The test successfully distinguishes between
learners at different levels of the CEFR
framework and appears to give believable figures
for learners’ level of vocabulary knowledge
The figures seem to mesh well with the
predictions for vocabulary suggested by the
coverage obtained from the frequency data
Next steps

This study is a first step in validating this testing tool
and in order to confirm its reliability, we intend to carry
out more tests at the end of this academic year.

We also have some supporting evidence that by using
coverage figures drawn from word frequencies, we can
tie the CEFR levels to vocabulary sizes in a whole
variety of languages other than English, French and
Greek. And that should help to make the CEFR system
both more robust and more transparent.
