The findings of this study show that to reach the suggested 95%–98% lexical coverage thresholds of the Digital Science Corpus (DSC) that are conventionally deemed to facilitate minimal and optimal reading comprehension (Laufer, 2020), middle school (MS) students grade 6–8 must recognize the first 6,000 and 14,000 most frequent word families in the BNC/COCA (Nation, 2012), respectively, plus proper nouns and marginal words. The results of the lexical analysis across the three sub-corpora in the DSC suggest that the Life Science sub-corpora has a considerably larger vocabulary load than the Physical Science and Earth and Space Science sub-corpora. Additionally, while 98.60% of the most frequent 1,000 BNC/COCA word families occurred at least six times in the DSC, the 2,000–7,000 BNC/COCA word families provided significantly fewer opportunities for repeated occurrence. Since more than half of the words in the 5,000–7,000 BNC/COCA bands occurred five times or less in the overall corpus, most words across these bands do not have high enough frequency in the digital science resources to allow MS students to learn them incidentally from reading the texts found in digital science resources.

Radiography is one medical setting where understanding patient information materials is particularly important in view of the rising numbers of examinations being performed and the potential risks involved from radiation, though studies consistently show that patients lack basic knowledge regarding the common radiographic exams. The gap in the literature and the concerns relating to patient understanding of radiation risk means there is a pressing need to investigate the linguistic characteristics and the language demands of radiography patient information, though to date very few studies have been carried out of the register and none that use a lexical bundles analysis. This study describes an analysis of 4-word lexical bundles in a corpus of 221 patient information leaflets for radiography which revealed a predominance of bundles more common to dense informational text and classroom instruction than the conversational, everyday language that healthcare writers are encouraged to use. A high frequency of passive structures - usually considered too complex for patients to process and flagged up by readability measures – was also found.

Among these linguistic features are lexical frames, or discontinuous word sequences (e.g. <em>the * of the</em>).
