English keeps certain words together, and knowing the pair is worth more than knowing each word alone. Every partnership below was counted across our whole published library, and earns its place by appearing far more often than two unrelated words of the same frequency would.
Shown as this reading writes them, with the form the library counts, what kind of pairing it is, and how often it occurs.
Every word in these five lines is listed here, and every one of them can be played on its own.

This page carries chapter 15 of How Two Boys Made Their Own Electrical by Thomas M. (Thomas Matthew) St. John exactly as it stands in the source edition, without abridgement. It runs to 215 sentences, grouped into 43 sections of at most 5 sentences so that a reader can take the chapter in steady, finishable pieces. The chapter also stores a coverage record mapping every one of its sentences to a part of the work, which is how the edition demonstrates that no line was dropped.
Work through the 43 sections in order, replaying any sentence and tapping unfamiliar words for their entries.
Each of the 43 sections in this chapter is short enough to read once, hear once, and then re-read with the vocabulary in view. Tapping a word plays it alone and opens its dictionary entry with IPA, part of speech and meaning, so the reader is never forced to guess a pronunciation from spelling. Working section by section keeps a long chapter from becoming an undifferentiated wall of text, which is the usual reason a reader abandons a work of this period.
Yes — every sentence and every individual word in chapter 15 can be played aloud in United States English.
Audio covers the whole chapter: any sentence can be played, and any single word within it can be played on its own. The voice uses United States English. For a work of this period that matters, because spelling is an unreliable guide to pronunciation for vocabulary that has fallen out of daily use, and a learner who guesses wrong tends to keep the error. Hearing the word in its own sentence, and then alone, settles it.
