As far as I can tell, [css-writing-modes] does not say anything about what the writing mode of a run of tate-chuu-yoko is. If that’s considered horizontal, it would be good to make that explicit, and if that’s considered vertical, we either need a new term to refer to from [css3-ui], or we need to single out this case. >>> >>> 9.1.2, Layout Rules[1] says this: >>> >>>> the glyphs of the combined text are composed horizontally (ignoring letter-spacing and any forced line breaks, but using the specified font settings), similar to the contents of an inline-box with a horizontal writing mode and a line-height of 1em. >>> >>> Is this explicit enough? >>> >>> [1] http://dev.w3.org/csswg/css-writing-modes/#text-combine-layout >> >> It is explicit enough to know what is happening in a combined text area, but I don’t think it gives me a word which means “horizontal in a horizontal writing mode and in a text-combine area inside a vertical writing mode, and vertical in other areas of a vertical writing mode”. >> >> What I am looking for is not an explanation of the behaviour (which we have), but vocabulary to refer to it. > I don't understand what the problem is, the text says "horizontal > writing mode". I can't read it otherwise. It says “similar to […] a horizontal writing mode”, which suggests that even though it behaves the same it might be called something else. The definitions of horizontal and vertical writing modes are: "A horizontal writing mode is one with horizontal lines of text, i.e. a downward or upward block flow. A vertical writing mode is one with vertical lines of text, i.e. a leftward or rightward block flow.” Maybe it is good enough, despite the lack of downward of upward block flow in a text-combine area. > If that's not enough for whatever reasons.

That sounds like it should work. - According to http://dev.w3.org/csswg/css-writing-modes-3/#text-baselines, "text-orientation: upright; writing-mode: vertical”, gives a vertical baseline. - According to http://dev.w3.org/csswg/css-writing-modes-3/#text-combine-layout, text-combine-upright has a horizontal baseline Florian
