Can Searching an Inflected Form Find the Root Word? Sometimes, Under Specific Conditions

Most of the time, yes. VocaX search folds inflected forms back to their base: type in a changed form and it does its best to look the word up under its root. Common changes — running for run, books for book, bigger for big — will usually take you straight to the root entry. Forms with irregular spelling, or forms that are simply rare, may not be found. When that happens, try another form, or look up the root directly; it normally takes a few seconds to settle.

1. When it does find the word

Search handles the kinds of change you meet most often in English:

• Plurals — books and boxes take you back to book and box.
• Tenses — walked and running take you back to walk and run.
• Comparatives and superlatives — bigger and biggest take you back to big.
• Third person singular — goes and watches take you back to go and watch.

What you land on is the root entry: definition, example sentences and pronunciation all live on that one entry. VocaX's main word list holds 74,334 words.

You type in a changed form and you get the root entry. That means you do not have to work out the base form first — just type the word as it appeared in the sentence.

2. When it may not find the word

In these cases search may not help, and another approach is quicker:

• Irregular changes — pairs like children and child, or mice and mouse, differ too much in spelling to be folded back reliably.
• Rare or seldom-used forms — the rarer the form, the less likely there is a match for it.
• Proper nouns — names of people, places and brands are outside what form folding covers.
• Abbreviations — these are handled as they are written, and do not necessarily lead back to the full form.
• Typos — a mistyped letter is "the wrong word", not "another form of the word", and search will not correct it for you.

3. What to do when it does not find the word

Try these three in order; the first one settles most cases:

• Drop the ending and search again — take off -s, -es, -ed, -ing, -er or -est and search what is left. running becomes run, bigger becomes big.
• Look up the base form directly — if you have a rough idea what the word looks like underneath, type that.
• Look up a different word from the sentence — if you met it while reading a passage, there is usually another word in that sentence you can look up.

There is also a way that saves effort: when you hit a word you do not know, translate the whole sentence first, then come back to the word. That way, even if a particular form is not found, you are not stuck.

Not finding it does not mean the word is missing from the dictionary. It usually means the form you typed could not be folded back — try another form and it generally turns up.

4. What to do once you have found it

Finding the entry is the first step. These are the steps that actually turn it into a word you know:

• Read the definition and the examples — check which meaning fits the sentence you were reading; English words carry several senses as a matter of course.
• Flag it — marking the word turns it into your next entry point for practice, so it does not disappear when you close the page.
• Practise the three formats separately — translation (spelling → meaning), dictation (sound → spelling) and speaking (spelling → sound) each train their own ability, so train whichever you are missing.

Words you have looked up stay in your search history, and when you want to work through a batch at once you can use that history as the source for practice.

5. Boundaries: where search does not help

• It folds word forms, it does not understand sentences. You type a word, not a sentence; paste a whole sentence in and it will not pick the unfamiliar words out of it.
• It is not a grammar tool. It will not tell you why a word changes the way it does, and it will not list every form of the word.
• It does not look words up from a meaning. If you want to know how to say something and do not know the English word, translation is the right tool.
• It does not correct spelling. If you mistyped, try another spelling.
• Proper nouns and abbreviations are outside its scope.

Think of it as a word box quick enough to keep up with you: type the word as it appeared, and most of the time it hands you the root entry. When it does not, try another form.

FAQ

Will searching "running" always find "run"?

Usually, yes. The -ing form of run is one of the most common kinds of change, and search folds running back onto run. If it does not come up this time, drop the -ing and search run directly.

Will searching "children" find "child"?

Not guaranteed. Irregular plurals like this differ too much from the base form in spelling to be folded back reliably. When it does not work, search child directly, or try another form.

Can I find an English word by typing its meaning?

Not really. Search works from the English form you type, not from a definition in reverse. If you know what you want to say but not the English word for it, translation is the more direct tool.

Do words I search end up in my reviews?

They stay in your search history, and you can later use that history as a source of words to practise. They are not pushed straight into today's review, though.

If I mistype a letter, will it still find the word?

Usually not. Search folds word forms; it does not correct spelling. If what you typed is a real form of a word, it will try to fold it; if it is simply mistyped, trying another spelling is quicker.
