Word-Opening Drill (re un con pre dis)
re un con pre dis inter over sub
Every passage contains: re un con pre dis inter over sub
QWERTY layout assumed. Backspace corrects; uncorrected errors count against net WPM.
"return", "unable", "connect", "prepare", "discuss", "interact", "overlap", and "subtract" all open with one of eight prefixes — "re-", "un-", "con-", "pre-", "dis-", "inter-", "over-", and "sub-" — rather than a plain, unmarked word beginning. Every one of these keystrokes follows directly on from a space bar press, which means the finger opening the word gets nothing to work with from whatever came before it: no preceding letter, no rhythm already running, no hand position the word itself set up in advance.
That's a different problem from the one the Consonant Cluster Drill covers. That drill is about which sounds are hard to fire in sequence — three consonants before any vowel arrives. Several of these prefixes aren't consonant clusters at all: "inter-" and "over-" both open with a vowel. What makes a prefix its own category isn't the sound, it's the position — every one of these eight openings has to be typed cold, at the exact moment a hand has the least information about what's coming.
Why This Drill
Fluent readers recognise a handful of prefixes on sight, because English reuses the same small set — "re-", "un-", "pre-", "dis-", "over-", "sub-" among the most frequent — across an enormous number of unrelated words. That recognition can work for or against a typist: knowing a prefix well enough to commit to it as a single planned unit is exactly what lets a hand type "un-" without waiting to see the rest of the word, but the same familiarity occasionally causes the wrong guess, when a hand starts producing a common prefix's motion on a word that doesn't actually begin that way.
This drill's ending-focused sibling, the Word-Ending Drill, gets to lean on a stem the hand has already typed — the ending arrives with momentum built up behind it. A prefix gets none of that. It's the first thing typed after the pause of a space bar, so whatever chunking advantage a common prefix offers has to come from recognition alone, not from anything the hand was already doing a moment before.
"inter-" and "over-" are worth singling out because they're also the longest openings in the set — four and five letters before any root material even starts. A long prefix typed cold is a bigger bet on that recognition paying off than a short one like "re-" or "un-", since there's more length for an early mistake to compound before the rest of the word gives the hand anything else to go on.
A Standing Start, Not a Hard Sound
The space bar is pressed by a thumb, which shares nothing in common with whichever finger has to hit the first letter of the next word. That handoff happens at the start of every single word on the site, but a prefix compounds it: several letters have to be produced in sequence, cold, before the reader-recognisable root of the word even begins, with none of the momentum a mid-word or word-final letter combination gets to borrow from what came right before it.
Why "inter-" and "over-" Break the Consonant-Cluster Assumption
It's tempting to assume a hard word opening always means a run of consonants, the way the Consonant Cluster Drill's "str" and "scr" do. "inter-" and "over-" show that isn't the whole story: both open with a vowel, with no consonant cluster involved at all, and both still have to be typed cold, right after a space. Position, not sound, is what all eight of this drill's openings actually have in common.
When Recognising a Prefix Helps, and When It Misfires
A hand that's used to firing off "un-" or "re-" on autopilot benefits from that familiarity most of the time — it can commit to the motion before the rest of the word is even read. Occasionally the same familiarity backfires: the hand starts producing a well-worn prefix's motion on a word that only resembles one, which is a different kind of mistake from simply not knowing where an unfamiliar letter sits.
Frequently Asked Questions
Why single out prefixes as their own drill instead of covering them as ordinary word openings?
Because every one of these eight beginnings has to be typed immediately after a space, with nothing carried over from the previous word — a different situation from an opening that happens to occur elsewhere in a passage, where the hand may already have rhythm running from the word before it.
Are all eight of these openings hard for the same reason?
No — "inter-" and "over-" both start with a vowel, so there's no consonant cluster involved at all. What the eight share is only their position: the first thing typed, right after a space.
How is this different from the Consonant Cluster Drill?
That drill isolates a sound pattern — three consonants firing in sequence before a vowel — wherever it happens to occur in a word. This drill isolates a position — the very start of a word, right after a space — regardless of whether the sound there is easy or hard on its own.
Can recognising a common prefix like "re-" or "un-" ever cause an error rather than prevent one?
Occasionally — a hand used to firing off a familiar prefix on autopilot can start producing that same motion on a word that only looks like it begins that way, which is a different kind of mistake from simply mistyping an unfamiliar letter.
Why are "inter-" and "over-" treated as harder than "re-" or "un-" in this drill?
Because they take longer to commit to. A five-letter opening is a lot of ground to cover before the rest of the word offers your hands anything to work with.
Does this drill pair naturally with the Word-Ending Drill?
Yes — one covers the moment a word starts with nothing behind it, the other covers the moment a word ends with everything behind it. Together they're the two edges of a word, and the Long Word Drill is often where both edges show up inside the same word.
