The three kanji 恵, 専, and 敷 share the same first 6 strokes. Using the traditional radicals I could describe them as being composed "一, 日, 丨..." at the start and then finishing "...心", "...寸", "...⼂, 方, 攵" respectively. Are the first 6 strokes derived from some older kanji? If so, does this kanji have a meaning and what would it be in Japanese?
Going back to kyūjitai,
- The first 8 strokes of「惠」and「專」share「叀」
- The first 6 strokes of「敷」uses「甫」
which are different components.
「叀」depicts an ancient type of ceramic tile used for weaving or spinning thread.

「叀」serves as two different phonetic components, which may hint at the original and extended meanings of「叀」in some characters:
- 「[叀]{せん}」 in「[專]{せん}」
- (Ceramic) tile is now written as「[磚]{せん}」
- To spin/turn is now written as「[轉]{てん}」(Shinjitai:「転」)
- 「[叀]{けい}」(Fanqie: 胡桂切) in「[惠]{けい}」
- Tassel is now written as「[穗]{すい}」(Shinjitai:「穂」);
- Fine cloth is now written as「[繐]{ けい}」
「甫」was originally「⿱屮田」, which depicted a vegetable (plants「屮」) garden (field「田」). This word is now written as「圃」.

Due to historical development, the characters/components「田」,「用」, and the top of「周」will appear as graphical variations of each other in the modern script.「用」is the shape that appears in the modern form of「甫」.
The character「[敷]{ふ}」meaning spread was developed through
- 「尃」, semantic「又」(picture of a hand; semantic variant「寸」) and phonetic「[甫]{ふ}」;
- Change to a shape variant「旉」;
- Addition of an action semantic component「攵」(picture of a hand holding a whip).
References:
So, actually 敷 has a different origin from the other two kanji.
Looking at wiktionary entry for 敷 in fact tells us that composition is comes from 旉攵
, the first of which is composed of 甫方
. Notice the importance of the extra ⼂
.
Doing the same for 恵 or 専 gives us 𤰔
. But actually more importantly is the note in wiktionary that, both those kanji are 新字体, aka Japanese simplifications of originals: 惠 and 專. Note how the part in question is now very different and is now this character: 叀.
As for the meaning, I'm not sure the meaning of these components is valuable to understanding the 3 characters above, but they can also be read on the wiktionary entries.
