The document lists common English verbs and their infinitive, simple past tense, and past participle forms. It provides some additional remarks on irregular verb forms and exceptions. Specifically, it notes that the verb "be" has two forms for past tense, certain verbs can be both regular and irregular depending on dialect, "lie" is irregular for reclining but regular for untruthfulness, and modal verbs are defective or incomplete.

Remarks:
1 The verb be has two forms in the simple past tense:
I, he, she, it→was; you, we, they→were.
.
2 The past participle of get is got in British English,
but gotten in American English.
3 Burn, dream, dwell, kneel, lean, leap, learn, smell,
spell, spill and spoil can be regular or irregular.
In British English, we usually prefer the irregular form
(burnt, dreamt, and so forth). Americans use the regular
ones, that is to say, the ones with -ed. As we have seen
above, a verb such as misspell should be treated as spell,
that is, Americans would say misspelled; but British
people, misspelt.
They are also pronounced differently:
dreamt /dremt/
dreamed /dri:md/
(Also kneel, lean and leap. Since leap ends in a voiceless
sound, -ed is pronounced /t/: leaped (/li:pt/),
but leapt (/lept/).)
spelt /spelt/
spelled /speld/
(Also burn, dwell, learn, smell, spill and spoil.)

3. 4 Lie is regular when it means ‘not to tell the truth’, but
it is irregular when its meaning is ‘to be in or put your
body into a horizontal position’:
She lied to me. (= She didn’t tell me the truth.)
She lay down a bit, as she felt sick. (= She put her
body into a horizontal position.)
5 The infinitive of the verb read is pronounced /ri:d/;
the simple past and the past participle, /red/.
6 Modal verbs are not included in this list because they
are defective, that is, they have not all the forms.
For instance, we may say I can play football (present
ability), or I could play football (past ability);
but we may not say I have could play football since I
was a child; we have to say I have been able to play
football since I was a child.
